On Beat the GMAT, Suzy explains how she finally got over the hump in Quant:
After I met [Erfun], I decided he knew his stuff, and, together, we did intensive Quant tutoring for 4 weeks, 4 hours/week. He was a great teacher, but what I found most beneficial was his ability to show me how to do questions efficiently by identifying what they were testing and immediately deciding on an approach for that question. He also helped me develop a great strategy for guessing and taking my losses on the questions above my level. With all this advice in mind, I finally took the exam on January 31, and scored a 730, with a 46 in Quant!!
Another Beat the GMAT success story, this time courtesy of Huang:
So, I took the plunge and hired a tutor. I looked around a few places and ultimately settled on GMAT Compass. If you’re not familiar with GMAT Compass, it’s a one-man tutoring company run by Erfun Geula, a guy whose grasp of grammar is incredible. We did our sessions over Skype, which was actually really effective. For each lesson, he would upload questions from SC 1000 or from mba.com, and we’d basically dissect the sentences. I learned a lot of really helpful tips for eliminating choices quickly and, really important for my situation, identifying what they were testing on each section. We also looked over Critical Reasoning and how to identify wrong answer choices and how to look at the more common question types. I think that the GMAT score ultimately comes down to the person taking it, but I found Erfun’s advice to be really helpful on test day, and I recommend him to anyone that needs.
