一、变与不变

1、题量分布

OG13版本总共包含了907道练习题目,其中749道来自OG12版本,158道为新加入的练习题目。其中,数学部分共有PS题目254道,包括了209道旧题与45道新题,DS题目198道,含旧题162道与新题27道。

语文部分,句子改正题目共158道,含旧题133道,新题25道,批判性推理部分共141道,含旧题116道,新题25道,阅读理解共156题,含旧题129道,新题27道。综合以上数据,新题约占OG13版本的六分之一。

2、答案解释

出现在OG12版本里面的题目,在13版本的解释完全一样,仅仅改正了一些上一版本的印刷错误。

3、关于新加入的题目

由于时间仓促,目前仅完成了部分题目的练习,发现部分属于GWD和PREP题目,目前可见的新题目大多具有一定难度

4、新题型:Integrated Reasoning

OG13版将提供50道新题型练习题目,但是题目将不出现在纸质的OG中,考生需要登录相关网站在线练习

5、题名排序

从OG11版本开始,OG中的题目排序按 GMAC声称的难度升幂排列,当然,GMAC认为的难度,和普罗大众认为的难度是否一致,还不是个定数。难度那些事儿,当做看野史,笑笑便好了。此次13版本中,有部分12版本老题目的排序发生了变化,不过这个变化除了有数字研究癖好的大仙感兴趣之外,对考生实在木有什么影响。
