對策：
扎實數(shù)學(xué)知識，計算時候不要出錯。
四、算分方法
目前的GRE考試單科分?jǐn)?shù)的區(qū)間為200-800分，10分為最小單位。改革后，GRE的語文和數(shù)學(xué)分?jǐn)?shù)區(qū)間將為130-170，1分為最小單位。新的算分方法有助于避免現(xiàn)行考試中多做對一道題導(dǎo)致分?jǐn)?shù)差十分這樣局面產(chǎn)生，讓分?jǐn)?shù)計算更加精準(zhǔn)更加合理。作文考試分?jǐn)?shù)區(qū)間依舊為0-6分，0.5分為最小單位。
對策：
這一項基本了解即可，我們沒有太多活動的余地，但新的算法會更科學(xué)，更客觀。
最后，新GRE考試雖然新，但未必難，希望同學(xué)們結(jié)合老GRE基礎(chǔ)實力的復(fù)習(xí)同時把握新題型特點，總和復(fù)習(xí)。相信有志者事必成，我們中國考生必將在新GRE考試中譜寫新的東方神話。
