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.
