Sat 数学历年真题

Dear Future University Student:

Thank you for purchasing The SAT Companion: MATH. We know how daunting the SAT test is, and we hope you find our companion guide to The Official SAT Study Guide, 2nd Editionuseful as you prepare for your test day. To use this book effectively to help you perform well on the SAT, we suggest the following steps:

TM

1. Buy The Official SAT Study Guide, 2nd Edition. The authors of this book are the creators of the test, and you will get no better practice than by doing these problems.

2. Review/Skim the subject chapters in The Official SAT Study Guide, 2nd Edition. The information in here should not be new, but it will be a good refresher.

3. Do problems, problems, and more problems!! Time yourself and take it seriously. Don’tlook at the answers until you have completed the section. Don’t cheat yourself! Did we mention do problems? 4. Use The SAT Companion: MATH as a reference. Again, don’t cheat yourself by

readinga problem in the book and then going right to the Companion explanation! Try these problems first, give yourself a real shot at completing them, and then while reviewing your score refer to the Companion to provide a detailed explanation. 5. Study frequently, in smaller chunks of time as opposed to one big block of time. Let’s sayyou have 2.5 hours per week to study for the SAT. If you commit to 30 minutes, 5 times a week, your resulting progress will be much better than if you spent 2.5 hours in one session. SAT practice is all about frequent exposure to problems. Note: 2.5 hours IS NOT our guidance on how much you should study per week. If you can study 5, 10, or 20+ hours a week, do it. We’ve written explanations in an easy-to-understand voice, and laid out the steps for each problem. We have not cut corners; the “easy” problems (is there really such a thing?) have explanations that are just as thorough as the hard problems.

The SAT Companion: MATH is a comprehensive reference guide. Whether you are reviewing this material with a Commonwealth Education tutor, in an SAT class, or by yourself, you will always be a click away from a complete explanation of the solution to a problem.

There are many ways to complete math problems; our method is surely not the only one! We have chosen our explanations as they make the most sense to us, but if you get to the same answer as we do by another method, please feel free to share it with us! We may not be
