Before Math Revolution, I was barely able to inch above q47-q48 on my practice tests. After taking the course, I scored Q49 on my practice tests with ease, eventually obtaining a Q50 on the real exam. Before taking Math Revolution, I used both Manhattan GMAT and GMATPill, but I was unable to secure the quant score I needed to get into competitive programs. The Variable Approach and Ivy Approach taught by the course was just what I needed to strategize on how to tackle each problem. Just be diligent with the videos and follow all of their methods. Good luck!
