今天还没有换题，数学大概有1/3的机经。先介绍我的感想 -- 我一战就复习了一两个礼拜，还不是全职的学，也没有看机经就近乎裸奔地去了。可想而知我被鸡宰了，那时我才恍然大悟我跟牛牛不是亲戚，八杆子也打不着。这次我准备了一个月，而且请了3天假在家学习。我认识到pace很重要，而且做题的感觉也很重要，我就天天做20-40道prep的SC和一套大全里的逻辑。这样我今天的pace还不错，作文，数学，和语文都提前4-5分钟做完了。经管我有些题的答案不太确定，但为了保持pace，我就选了一个我认为比较好的答案继续下一题。 我觉得这次的逻辑题相对比我上次考的难，有那么一两道更像LSAT的题，不知是不是测试题。 AWA AA: The country of Sacchar can best solve its current trade deficit problem by lowering the price of sugar, its primary export. Such an action would make Sacchar better able to compete for markets with other sugar-exporting countries. The sale of Sacchar’s sugar abroad would increase, and this increase would substantially reduce Sacchar’s trade deficit.
