The Best SAT Score Predictor

The Best SAT Score Predictor SAT / ACT Prep Online Guides and Tips The SAT can be mysterious and nerve-inducing; your score on this never-before-seen test will play a hugerole in your college applications. When I took the SAT for the first time, I didn’t do any preparation and wasn't sureI could reach my target score. The best way to lessen yourfear is to try to predict your SAT score. How can you estimate your SAT score? What are the effective methods? Do the SAT score predictor quizzes really work? This guide will walk you through the different methods of estimating your SAT score and will tell you how to use that prediction. The Best Way to Predict Your SAT Score The best method to predict your SAT score is to take a full-length official College Board SAT practice test under real testing conditions.It’s a big time commitment - over four hours - but it’s the most accurate SAT score predictor. Where Can You Find a Practice Test? All of the official SAT practice tests created by the College Board are available for free online.I’d recommend you pick one and print out a copy of the test since you'll be taking the real SAT with pencil and paper. How Should You Use the Test? To get the most accurate score prediction, you want to mimic the real test as closely as possible.This means you cannot use your phone, computer, dictionary or any other outside help.You should only have pencils, an eraser, a pencil sharpener, and a calculator on your desk. Stick to the exact timing.Note: the time allowed is printed at the start of each section.Use a watch to time yourself, anddon't give yourself any extra time. An extra minute or two could artificially increase your score.Also, you’re only allowed to work on that section during the allotted time. Don’t move on to the next section if you finish early, and don’t go back to a priorsection. How Do You Score the Test? Score it using the instructions on the College Board website.You’ll start by calculating your raw score, which is simply the number ofquestions you answered correctly. Then, you use that raw score and a chart provided by the College Board to calculate a scaled score for each section.That scaled score is your estimated SAT score! Note: This is only a baseline SAT score. You can raise your score with dedicated prep. To do so, you should create an SAT study schedule, which I discuss more below.If you're looking for a startingpoint for your SAT prep, check outour free SAT studyguide. Don't have time for an SAT practice test? We've got other options! What Are Other, Less Time-Consuming SAT Score Predictors? Did you takethe PSAT or ACT? If so, you canuse thatscore to estimate your SAT score. These tests are useful predictors because the experience of taking them is similar to the SAT: early in the morning, in a classroom with other students, without outside help, etc. Below I’ll give an overview of how to use the PSAT and ACTto predict your SAT score. PSAT It’s the next best thing to taking an official SAT practice test.The PSAT was written by the College Board, the same company behind the SAT.It’s very similar to the SAT; the name literally means preliminary SAT. The College Board meant for your scaled PSAT score to be an estimated SAT score.However, since the PSAT is intended to be a precursor, the College Board designed it to be slightly easier than the SAT.The PSAT is scored on a scale between 320 and 1520.It doesn't go up to 1600 since the SAT is a more difficult test than the PSAT.While a 1200 PSAT score suggests you might score around 1200 on the SAT, a perfect PSAT score doesn't necessarily guarantee a perfect SAT score.This is why the PSAT scale is shifted down from 1600 to 1520 to account for the differences in difficulty. Pros The PSAT was written by the same company as the SAT. It was designed to match the SAT format. It was created for the purposing of estimating your SAT score. It's administered in similar conditions asthe SAT. Cons It’s slightly easier than the SAT, so it will not be as challenging. It may not be able to accurately predict scores for top performers in the 1500-1600 range. ACT Score If you took the ACT, you use thatscore to predict your SAT score.There are simple conversion tables that will take your 1-36 composite score and convert it into a 400-1600 SAT score.However, this is a less reliable method than using a PSAT score. While the ACT is astandardized test similar to the SAT and PSAT, the ACTwas created by ACT, Inc., not the College Board.There is overlapping content between the SAT and ACT, but the content is not exactly the same.For example, the ACThas a science section while the SAT doesn’t.Also, the SAT has a no-calculator math section while the ACT doesn’t. If you use your ACT score to estimate your SAT score, the prediction may be off by up to 100 points.For example, I got a 34 on my ACT, which would predict an SAT score between 1490-1530, but, in actuality, I got a score of 1420; 70 points less than the lowest estimated score.Some students simply perform better on the ACT than the SAT. Pros The ACT is astandardized test that is designed to estimate college preparedness like the SAT. Itcovers similar Math, Reading, and Writing content as the SAT. It's administered in similar conditions as the SAT. Cons The ACT was not written by the College Board. Itdoesn’t cover the same material as the SAT. Predictions may not be exact (could be off by up to 100 points). It's difficult to accurately compare the ACT to the SAT. Don't trustother "predictors." What Won’t Be Good SAT Score Predictors? I’d recommend avoiding any method not mentioned above. Here are some of the more commonly used SAT score predictors that I wouldn’t recommend. Non-Official Practice Tests Non-official SAT practice tests, aka those not written by the College Board, will not give you a realistic estimate of your SAT score.This includes full-length non-official SAT practice tests as well as any shorter SAT score predictor quizzes.These tests are too different from the SAT to give you a good prediction; theydon’t accurately mimic the SAT test format and typically don’t cover the same content as the SAT. You could end up with a score hundreds of points off from how you'd score on the actual SAT. GPA Some students try to look at their GPA and guess their SAT score. It’s tempting to say that because you have straight A’s, you'll obviously get a 1600 on the SAT. On the other hand, if you have a low GPA, you might feel doomed to a low SAT score. However, GPA doesn’t always correlate with SAT score.Some students with low GPAs end up with great SAT scores while others with high GPAs end up with low scores. Don't try to estimate your SAT score using GPA. AP/IB Tests AP and IB exams test very specific content such as Biology, Economics, Calculus, and History.Most of this content is not covered on the SAT. Therefore, excelling on your AP or IB exam will not necessarily correlate with SAT success. No matter your prediction, don't be a grumpy kitten! How Should You Use Your Score Prediction? If you have an SAT score prediction, how do you feel about it?If you’re unhappy, you should create an SAT prep scheduleto help you reach your score.Below is a rough estimate of how many hours you need to devote to studying to achieve certain score improvements. 0-50 SAT composite point improvement: 10 hours 50-100 point improvement: 20 hours 100-200 point improvement: 40 hours 200-300 point improvement: 80 hours 300-500 point improvement: 150 hours+ Check out our ultimate SAT study guide to help you get started with your SAT preparation. If you’re very happy with your predicted SAT score, you should still do some SAT prep,but not as much.I’d recommend studying for at least 10 hours.Take two practice tests with in-depth reviewto get comfortable with the test format and to make sure your practice test scores align with your target score. Whether you have a score estimate or not, remember that no predictor is 100% accurate, not even taking an official SAT practice test.You should plan to take the real SAT more than once, so if you don’t reach your target score the first try, you have another shot.

Cohesion Definition and Examples in Chemistry

Cohesion Definition and Examples in Chemistry The word cohesion comes from the Latin word  cohaerere, which means to stick together or stay together. In chemistry, cohesion is a measure of how well molecules stick to each other or group together.  It is caused by the cohesive  attractive force between like molecules. Cohesion is an intrinsic property of a molecule, determined by its shape, structure, and electric charge distribution. When cohesive molecules approach each other, the electrical attraction between portions of each molecule holds them together. Cohesive forces are responsible for surface tension, the resistance of a surface to rupture when under stress or tension. Examples A common example of cohesion is the behavior of water molecules. Each water molecule can form four  hydrogen bonds with neighbor molecules. The strong Coulomb attraction between the molecules draws them together or makes them sticky. Because the water molecules are more strongly attracted to each other than to other molecules, they form droplets on surfaces (e.g., dew drops) and form a dome when filling a container before spilling over the sides. The surface tension produced by cohesion makes it possible for light objects to float on water without sinking (e.g., water striders walking on water). Another cohesive substance is mercury. Mercury atoms are strongly attracted to each other; they bead together on surfaces. Mercury sticks to itself when it flows. Cohesion  vs. Adhesion Cohesion and adhesion are commonly confused terms. While cohesion refers to the attraction between molecules of the same type, adhesion refers to the attraction between two different types of molecules. A combination of cohesion and adhesion is responsible for capillary action, which is what happens when water climbs up the interior of a thin glass tube or the stem of a plant. Cohesion holds the water molecules together, while adhesion helps the water molecules stick to glass or plant tissue. The smaller the diameter of the tube, the higher water can travel up it. Cohesion and adhesion are also responsible for the meniscus of liquids in glasses. The meniscus of water in a glass is highest where the water is in contact with the glass, forming a curve with its low point in the middle. The adhesion between the water and glass molecules is stronger than the cohesion between the water molecules. Mercury, on the other hand, forms a convex meniscus. The curve formed by the liquid is lowest where the metal touches the glass and highest in the middle. Thats because mercury atoms are more attracted to each other by cohesion than they are to glass by adhesion. Because the shape of the meniscus depends partly on adhesion, it will not have the same curvature if the material is changed. The meniscus of water in a glass tube is more curved than it is in a plastic tube. Some types of glass are treated with a wetting agent or surfactant to reduce the amount of adhesion so that capillary action is reduced and also so that a container delivers more water when it is poured out. Wettability or wetting, the capacity for a liquid to spread out on a surface, is another property affected by cohesion and adhesion.

Sociology of the Family Essay Example | Topics and Well Written Essays - 1750 words

Sociology of the Family - Essay Example The secondary stage of socialization usually takes place outside of the home, it can be at school, with peers or at a workplace - this is when most people begin will to socialize with people from different cultures (Laslett, 303). During this stage you may gain achieved roles such as getting a good job or becoming a mother/father and the changes in trends are recognized too from the jargon that is used, to the seasonal change in fashion trends. Norms are the things we are expected to do as they are regarded as being normal, values on the other hand are the principles we follow but we tend to take for granted e.g. writing. If a person breaks the norm then they are deviant and agencies of social control such as the police take over. These basic fundamentals are recognized by most people nowadays and explain why there arent as many cultural conflicts as there has been in the past. An example of cultural conflicts is during the early 19th century when White Americans came into contact with Native Americans - many conflicts and a few massacres had taken place simply because most of the White Americans were not willing to socialize and understand this Native culture (Kain, 955). A general perception of sociology is that it is the same as psychology. This is only correct to an extent, both the subjects are a part of social science and they look into the behavior of people (Bar-Yosef, 69). However, the difference is that psychology is the study of the mind and its mental states, whereas sociology looks at people on a broader scale, as it looks at the study of the structure and development of human societies. Today families are confronted with many problems. One issue is the imbalance in household and childcare labor done by men and women (Haralambous, 5). Another problem facing families today is the sharp rising in the number of elderly people. Changes to society may help fix some of these issues. Although society has made

Collaboration Photography Assignment Example | Topics and Well Written Essays - 250 words

Collaboration Photography - Assignment Example The scene is mechanical, and captivating at the same time, and through right angle shoots outs the object confronts the subject directly and the use of light and shadow brings more focus on the object. Though people consider black and white photography is often treated as the poor relation of color, it can make a photo look captivating. A distraction brought out by color in the photo is eliminated by the use of the black and white photography; a studio brings out the best of the colors. In fact, the black and white boils to major concepts: removal of distraction, contrast, pattern, texture and lighting. Color photography unlike the black and white one does not effectively provide patterns, in fact, slight ones go unnoticed. On the other hand, a black and white Photoshop provides more vivid capturing patterns, as the viewer’s attention is more focused on the shapes formed by the elements in the

The Microsoft Case: Protecting Competition or Competitors? :: Business Management Economics

The Microsoft Case: Protecting Competition or Competitors? "When a company of merchants undertake, at their own risk and expense, to establish a new trade with some remote and barbarous nation, it may not be unreasonable to incorporate them into a joint stock company, and to grant them, in case of their success, a monopoly of the trade for a certain number of years. It is the easiest and most natural way in which the state can recompense them for hazarding a dangerous and expensive experiment, of which the public is afterwards to reap the benefit. A temporary monopoly of this kind may be vindicated upon the same principles upon which a like monopoly of a new machine is granted to its inventor, and that a new book to its author." -Adam Smith, Wealth of Nations, 1776 Introduction Protecting the competition, not the competitor, has become a commonly used statement in recent interpretations of the Sherman antitrust acts of the late 19th century. Such words, however, were not used in the preliminary decision of the U.S. v. Microsoft monopoly case. Just recently, U.S. District Judge Thomas Penfield Jackson cast Microsoft as a "voracious monopolist that has hindered innovation, harmed consumers, and run roughshod over its rivals." (Chandrasekaran, 1999: 1) A 207-page "findings of fact" report did not conclude whether Microsoft violates the Sherman Antitrust Act. The report suggests, however, that Microsoft is indeed a software hog with a decade of at least 90%-95% control of the Windows market share. Chief Executive Officer Bill Gates said he respectfully disagrees with a number of the court’s findings. "In the end we’re quite confident that our integrity†¦and the benefits we provide consumers will be upheld." (Chandrasekaran, 1999: 1). It seems that in an effort to protect the consumer, the government may have forgotten the power of the consumer’s dollar. Perhaps Microsoft has control of the market share because the product is superior to all others, and consumers know it. Is it possible that the government would be punishing the consumer, if in fact consumers truly are happy with the Microsoft product, and have chosen to buy it, not because Microsoft has a significant influence on the market, but because the product is more advanced? What makes a product superior to another? Vision, innovation, risk, marketing: the same elements that Adam Smith praises in a new venture, then rewards, if successful, by granting the company a temporary monopoly in the market.

Economics and Ethics

The area of ethics in economics is a divisive one, over which there has been considerable debate. Ethics has many interpretations in the history of philosophy as well as in economic history. Very simply, ethics refers to an understanding of certain forms of behavior as either right or wrong. â€Å"The field of ethics, also called moral philosophy, involves systematizing, defending, and recommending concepts of right and wrong behavior.† (Ethics) However, there are many complex aspects to the understanding of ethics. An early idea of ethics was put forward by the philosophers Jeremy Bentham and John Stuart Mill in the 19th Century. They suggested that ethical action was concerned with providing â€Å"†¦ the greatest balance of good over evil.† (Ethics) On the one hand, economics is fundamentally driven in a systems and practical sense by the need to acquire profit and accumulate wealth. On the other hand there is a growing debate about ethical responsibility and integrity in the business and economic world, with respect to aspects and issues that strictly fall outsider the ambit of the pure science of economics per se. Recent controversies, such as the Enron scandal have also highlighted the issue of ethics in economics and business. This leads to a vast array of issues and questions; such as the protection of future resources and the growing debate about the reality of environmental ethics as it relates to purely economic concerns. Questions are asked such as; can there ethically be a case for unconstrained economic adventurism and profiteering without paying attention to the moral and ethical dimensions of these actions? The debate and the dilemma that business faces in terms of ethical practices and views are concisely expressed in the following quotation. While â€Å"Businesses, in some parts of the world, have become integral participants in such causes as protecting the environment and alleviating poverty from economically depressed localities†, this concern with ethics is â€Å"†¦ confronted with the problem that economists have no other way to approach reality without concentrating on questions of utility.† ( Zaratiegui J. 1999) It is this focus on utilitarianism and the profit margin central to the capitalistic mode of economic production, which brings it into conflict with other issues and views and often results in a negative ethical assessment of business and economics. Therefore many critics are of the opinion that in an ethical sense the utilitarian focus of modern capitalism should be criticized. More importantly, theorists note that, â€Å"The nature of modern economics has been substantially impoverished by the distance that has grown between economics and ethics †¦ [economics] can be more productive by paying greater and more explicit attention to the ethical considerations that shape human behaviour and judgement.† (Sen, A. 1987, p 7.) It should also be noted that this debate and the alleged dissociation between economic thought and praxis and various ethical and critical stances, is a fairly recent phenomenon. In its origins modern economics was intimately connected to ethics and ethical motivations. Sen reminds us of the contrast between the â€Å"non-ethical† feature of modern economics and its genesis as an offshoot of ethics. At the time of its inception, then, the language of economics was comprised of normative elements. Nevertheless, over time, economics came to be considered an autonomous science, and its language and value judgments become increasingly more â€Å"positive.† It is this change in economic thought and praxis and the move towards a neutral or † value free† attitude towards ethical issues, with science as the motivating example, that has essentially created the present debate. However the debate about ethical involvement and responsibilities in economics continues to vacillate from one point of view to the other. On the one hand, economists argue that economic praxis and associated analytic techniques are ethically positive in that they help to predict human social and economic growth and development in a consistent way. Economists are also quick to argue and provide examples of the way that economic strategies uplift, develop and form a common basis for world interaction and harmony. â€Å".. it is regarded by some as beneficial, enabling economists to develop analytic techniques and make rational predictions of future human behavior. â€Å"(Zaratiegui J. 1999) On the other side of the argument there are many who interpret the alleged benefits of economics rather as the promotion of profit over ethical norms and principles. However in recent years there has at least ostensibly a reassessment of the ethical parameters of economics from within the economic community. As recently as a decade ago, many companies viewed business ethics only in terms of administrative compliance with legal standards and adherence to internal rules and regulations. Today the situation is different. Attention to business ethics is on the rise across the world and many companies realize that in order to succeed, they must earn the respect and confidence of their customers. This change is still based in the praxis of customer behavior and reaction but nevertheless it does show a change towards a greater awareness of ethical responsibly ion the world. Many of the ethical debates surrounding economics revolve around the complex issue of the interactions of business and commercial concerns and bio-ethics. Bio-ethics refers to the ethical demands and requisites in the interaction between the human and the non-human environment. As such, bio-ethics is difficult to relate to or argue in purely subjective or human terms; which make it all the more difficult to understand and react to from an economic perspective. A case in point which is still under discussion is the intended use of the oil reserves in the Arctic Wildlife Refuge. At present the debate about the exploitation of the Arctic National or ANWR has been in process for 20 years. (Endless debate drains political energy) The debate has tended to centre mainly on the exploitation of a sensitive ecological area as opposed to the economic and political value for the country from a potentially rich oil supply. The divergent viewpoints are expressed in the following assessment of the situation. To generalize, people who care most about the wildlife and wilderness don't give a hoot about the oil; folks fixated on the oil think its value outweighs the wildlife and wildland concerns. The two sides are every bit as polarized and only a little less passionate than those battling over abortion rights† The National Petroleum Reserve of Alaska (NPR-A), is situated between the foothills of the Brooks Range and the Arctic coastline, and is about 120 miles from the Arctic National Wildlife Refuge (ANWR). (Rosen, Y. 2003. ) The Bureau of Land Management ( BLM) estimates the area will†Ã¢â‚¬ ¦ supplement production from the Alpine fields, which hold 429 million barrels and have a daily oil output of about 100,000 barrels.† (US OKs Commercial Drilling in Alaska Oil Reserve) From an economic point of view, the use of this oil reserve will have many positive aspects. Besides the money that would be brought into the economy instead of flowing out in oil purchases, it would have positive internal and political implication as it would obviously mean less reliance on outside oil sources. The Energy Information Agency of the Department of Energy estimates that Alaska oil production averaged 902,000 barrels of oil per day from January through August 2004, about 16 percent of total U.S. oil production during that period, most of which comes from Prudhoe Bay. Opening up even a limited area of ANWR for drilling would offer the prospect of producing from Alaska possibly 40 percent or more of the oil consumed in America. This view can be seen as supporting the idea of an ethical position in the economic exploitation of the region in that it will be for the â€Å"greater good† of the international community to reduce America's oil dependencies. The other side of the argument is that the exploitation of this region for profit will upset the delicate ecological balance and will further have a larger ecological impact. From this point of view the proposed economic actions are unethical. In essence the debate is centered on two very different world views which need an understanding of their underlying biases to be fully comprehended. Many similar points of dissention and lines of argument are formed in the ethical debate that has raged for years about animal experimentation for research. One has the argument for experimentation on the basis of ensuring human safety; while those opposed point out that this view still contravenes basic bio-ethics and the respect for life on this planet. On the one hand business and commerce stress the need to test products before public consumption and on the other hand activists state that many of these tests are simply attempts to placate the public and have no intrinsic scientific worth. Animal rights groups point out that animal experimentation is an extremely cruel endeavor. Among the many different types of animal extermination are the†Ã¢â‚¬ ¦ the toxicity and irritation testing of various consumer products, such as foodstuffs and cosmetics†¦extraction of products, and the development of drugs.† (Rollin, 1992, p. 136) One of the most criticized tests in this regard is the Draize eye irritant test. This test involves â€Å"†¦ placing a substance in the eyes of four to six rabbits and evaluating the effect.† (Thompson 1988, p15.) The results for these extremely cruel experiments are used for cautionary labels on various products such as soaps and cosmetics. One of the main arguments against commercial vivisection is that many scientists claim that there is no real scientific purpose to animal experimentation. This is a particularly the case with regard to animals which are used by pharmaceutical and chemical companies to test the toxicity of drugs and other substances, including cosmetics and household cleaners. This practice has been regularly criticized by doctors and scientists who are of the opinion that these experiments are not only unscientific but also flawed in many respects and even dangerous to human health. Countering these assertions the economists point to the many successful trials that have resulted in positive results and benefits for human beings and human health. The economic world is, as has been stated, becoming more aware of its ethical responsibilities. Some critics still see this new found ethical responsiveness in the scientific and economic communities as a reaction only to pubic opinion and customer perception. However there are also those who are more positive and who think that the economic community is becoming more aware and reacting more positively to the important ethical dimensions of their activities.

My Own Developing Pedagogy Gravitates Towards The Steiner...

Introduction Being that the nation should not be valued upon it’s wealth but upon it’s education and character, my own developing pedagogy gravitates towards the Steiner model founded in understanding of the children’s developmental needs, rather than a standardised content based syllabus as is the State Government model. I see Steiner as a balance between student centred approach (progressive) and what is traditional (essential). Although I imagine everyone is trying to obtain the same goal, the way in which this is being achieved is vastly different. I choose to focus on the Steiner model as it stresses teaching content at the appropriate time and in a way that is compatible with the children’s natural style of learning at that age. The following principles support the theory and explains the motivations. By contrast I will briefly look at a historical example juxtaposed with modern global standards (OECD). Principles You could state that Steiner loosely supports the core points of a progressive philosophy. That all students play a role in forming the content of the curriculum meaning the teacher works cooperatively with the students to form lessons based on capacity, interests and curiosities. And, with every child being an individual, with natural gifts; each may follow a similar developmental path, but at different rates. The Steiner class teacher system, where one teacher stays with the class for eight years, allows continuous monitoring of each student’s progressShow MoreRelatedDeveloping Management Skills404131 Words   |  1617 Pageshelps you actively study and prepare material for class.
