This is one of oldest tricks or lies from Chinese students. When they scored well on an exam, e.g. GMAT, or GRE, they would tell everyone that they did really study or (studied for like 10 days) and got 700+ and that if they were to study a little harder they would score even better. But, as you know, this is nothing from the truth, a lot of them actually have studied like crazy by themselves with telling anyone. By doing so, they will get more "respect" to fellow students.
My advice is to ignore some of the ridiculous posts in which the LZ purposely tried to tell 1) how easy the test was 2) how un-prepared that he/she was when taking the test but still able to pull off a scored like 740 in the end.
