菜鸟考gmat 求助
刚想准备考GMAT，没报班，看了OG，对于data SUFFICIENCY,PROBLEM SOLVING, CREITICAL REASONING 用中文分别叫什么题啊。还有DATA SUFFICIENCY是做什么的。没看懂。怎么做，例如 if the length of Wanda's telephone call was rounded up to the nearest whole minute by her telephone company, then Wanda was charge for how many minute for her telephone call. (1)The total charge for Wanda's telephone call was $6.50 (2) Wanda was charge $0.50 more for the first minute of the telephone call than for each minute after first. 请问选A OR B OR C OR D OR E 还有各种题型分别要用多少时间，请帮忙。谢谢[ 本帖最后由 dshallan 于 2008-10-3 11:24 编辑 ] 第一，为什么非要把一个英文名词翻译成中文？你知道它英文什么意思不就够了吗
第二，data sufficiency的具体内容在OG上有详细的解释
谢谢
