I first started studying for the GMAT using a Kaplan online course. I studied for months, putting in countless hours every week in between work. It was exhausting and when I finally took the test, I scored a 640 total (44 in Quant), far below my target score of 700-720 to be competitive for top MBA programs. Clearly, I needed to rethink my studying strategy. I did some research and came across Math Revolution and saw rave reviews for the program and Hee Jean Kim, with great pricing options that were much more affordable than the competition (seemed too good to be true!). I signed up and it was the best decision I could've made. Hee Jean is an incredible tutor: reliable, flexible and supportive. He teaches a completely different method for approaching the GMAT Quant section than I had seen before. He gave me an excellent study plan that helped structure my time and focus, which I had been sorely lacking before. After about 3 months of studying with Hee Jean, I retook the exam and scored a 740 (Quant 49), above what I had hoped for. I cannot recommend Math Revolution and Hee Jean more highly!
