In order to hit a high score(Q49-51) in GMAT Math, it is critical to learn hard and hardest DS questions determining a score of 49-51. To tackle these questions, we recommend you learn our Variable approach for DS that is significant time saving, a short-cut approach. Especially, you need to learn so called CMT(Common Mistake Types 3,4). You will encounter 4-5 CMT questions in actual exam. If you get a half of them correct, you hit 49.
If you get 1-2 of them wrong, you hit 50. If you get all of them correct, you hit 51.
Also, focus on 5 key topics (Integer, Statistics, Inequality, Probability, Absolute Value) that account for 80% of GMAT exam.
