　　SAT数学对于中国考生相对简单，下面为大家整理的是关于SAT数学备考的方法，总体而言是从整体备考的战略以及部分备考的方法的角度进行的介绍，非常详细，大家可以在备考自己的SAT数学考试的时候进行适当的总结和应用。

　　Strategies for Math

　　For math, the best preparation is to do math. Make sure to keep up with your homework in school, take math AT LEAST through Algebra 2, and try your best. The more math you do, the more comfortable you will be when the SAT arrives.

　　Of course, there are certain strategies for the exam that are usul:

　　Estimation

　　If a particular diagram is drawn to scale (which they always are unless otherwise specified), then use common sense. Get rid of answers that look too small or too big. Try to figure out the relative largeness of a value with respect to the choices if you can&apost directly solve the problem.

　　DRAW!

　　I cannot specify how important this strategy is. It&aposs not only a strategy, it&aposs a necessity. If you find there&aposs a weird geometric figure that you&aposve never seen bore and don&apost know how to tackle (for area, perimeter, etc.), then DRAW LINES! Try to break it into things you know how to work with or try to extend things to make something you&aposre familiar with. Make sure to mark angles, sides, etc. Geometry problems should be thoroughly written all over when you&aposre done.

　　Plugging in

　　It&aposs multiple choice! What better way to find which choice is correct than to test them out? For something you can easily tackle, don&apost bother, as this method is inficient. But for something that is difficult, then just try to plug in to see what works. At worst, you&aposll eliminate the blatantly wrong answers, and at best, you&aposll eliminate all the wrong answers.

　　Simplification!

　　Another really important one. If you get a really long expression or quotient, odds are, you&aposre meant to simplify it. Usually just cancelling out a factor or two will magically yield what you&aposre looking for. Oh, so satisfying!

　　Factoring

　　Always, always be able to recognize how to factor/unfactor something. Many times those intimidating numbers & operation problems can be solved if you just factor or unfactor. Learn things like the expansion of (a+b)^2 and how to undo its expansion to get this. With practice, this becomes second nature and you gain a LOT of points!

　　Substitution

　　Learn to recognize when to plug in one quantity for another. Usually this solves a great number of the harder problems.

　　For a review of the actual mathematics, the Official SAT Study Guide provides a fairly good rresher. I suggest that almost everyone work through it -- there&aposs always something you never learned/forgot, even if you&aposre in upper level math.
