It's been a decade since I've been in school, so to say that I was unfamiliar with the concepts tested on the quant section is an understatement. TTP helped me to get back to the basics and build my quant skills from basically non-existent to a solid understanding. I highly recommend it for anyone looking to improve their quant score. The creator of TTP, Scott, was also incredibly helpful and supportive throughout the process. It's apparent that he cares about each of his students and he took his time to explain to me the importance of taking a strategic approach with studying for the GMAT, and of course exactly what that strategy is. He also offers one-on-one tutoring for those who are looking for more hands on support.
