Like swimming, the last half second is the hardest to improve.

For SAT, every 10 points improvement from 2200 is several times harder than 10 points improvement from say 1800.

• SAT是能力测试，智商测试，还是知识测试？ -cutedolphin- ♂ (0 bytes) () 04/29/2015 postreply 08:48:05

• percentile来说，排在后80%是比知识，前3-20%是比能力，前3%之内是比运气 -keessa- ♀ (0 bytes) () 04/29/2015 postreply 09:16:03
