谢谢所有的同学, 让考试变的不再痛苦!


这么多年, 考了GRE, LSAT, GMAT, 不停的找自己的职业方向, 终于明白梦想和坚持, 缺一不可. 有句话说的好, 十年后的你, 一定会感谢你今天的努力!

楼主算了5分钟也没出来, 建议大家在家算好,


2. 58 inches = 14 horse 2 inches = 14.2 horses, C has a pet with height of 15. 3 horse last year, this year it increases 3 inches, what is the height of the animal this year?
A. 15.6 houses
C 16.2 houses
选 C , reasoning: 58 inches = 14 house 2 inches, so 4 inches = 1 house, so 15.3 houses= 15*4+3 =63 inches, this year it will be 63+3=66 inches, which is 16.2 houses,
Please pay attention to A, which is not correct, since in this measurement, once it reaches 4 inches, it will add to 1 horse, "逢4进1"!!!


3. DS, on a party the guests will have prezels, cheese cake or dry fruit, at least one of the three, or more, how many people has cheese cake and dry fruit?
