the princeton review的GRE教材
我个人觉得准备GRE不能太理想化，可以考虑在有限的时间内做尽可能多的真题。这三本书我并没有看过，帮不上你，但是原则是尽可能多地做真题，不用在选择什么材料上耗费太多的时间。
推荐楼主去看看尚友GRE留学文库，里面有很多关于GRE的各种资料和课程，挺全的，可以直接下载的，希望对你有用~~
princeton review 的2009-2010版SAT2 math1&2 里面竟然没有讲微积分吗！
据我所知，princeton review and barrons 的 sat 2 math 1 and 2 里面没有讲到calculus。基本上， math3 里面不需要用到calculus.However, if you have already studied calculus or take calculus AP, it might be easier and quicker if you use calculus to solve certain questions. For example, f(x)=X , from the domain (0,0) to (5,0), rotate the function around the x-axis. For this kind of question, it may be easier to use integral to solve, but you can still solve it using basic geometry.From my experience, there is only this one question type that calculus can apply.Therefore, there is no need to learn calculus if you are only taking sat math.Also, my suggestion is that buy the barrons sat2 math level 1 and 2 book because princeton review is a bit easier than the real exam. Many of my friends, including me, got 800 in level 2 by working on the practice test at the back of barrons in less than 3 weeks. If you have any more question about sat or sat2 or ap , i am happy to help you
