First of all, I want to say how excited I am to be writing this review right now. I looked at the course reviews all the time and told myself that once I finally got the score that I wanted that I would write a review to help calm and motivate other GMAT test-takers. Before I began using Target Test Prep, I had been studying for roughly 2 months and seemed to be stuck around Q44. I've always been pretty good at math so I was a bit shocked when using some of the recommended book series didn't get me to where I wanted to be. I knew that I was capable of better than a Q44 and also knew that I needed at least Q48 to reach the score range that I had set for myself. I began to look around on GMATClub and other GMAT related sites to see if there was product focused solely on the quantitative section of the GMAT and that had consistently good results. After reading the reviews of TTP and learning about the 5 day trial for just $1, I figured it was worth the shot. I was immediately hooked as soon as I began using the platform. It's very intuitive and easy to use. It makes the math simple and easy to understand and includes more practice problems than one could ever possibly need. I did the entire program and answered every problem the course had to offer over the span of about 3 months while simultaneously meeting with Jeff Miller (one of the TTP tutors) once a week. All I can say is that the program works, especially when coupled with Jeff Miller (seriously Jeff is the man and knows how to spot your weaknesses and fix them). If you're willing to put in the time and make the commitment then there is no reason you can't achieve a Q47+ using this program. I'm living proof. Good luck!
