I bought og12th, and og quantative. if I finish both these 2 books and review it before the test will I get a high marks?
I am in China, We have a forum called chasedreamer.com. some of successful exam takers who got very high makrs on GMAT posted their successful test stoies. they said that they reviewed the questions taken by former test takers on actual GMAT test days get very high marks since the question stock won't change. Is that true, does it really help.
I really want to improve my math ability, how can get I do that in a short time.
