I began studying for the GRE in June 2019 using a variety of unhelpful programs. I took my first GRE in October and was unhappy with my quant score. I researched the best GRE courses to help raise my quant score, and I decided to give TTP a try. TTP was reasonably priced, and I liked the structure of it. I cannot say enough great things about how helpful TTP was in preparing me for my GRE. The explanations to the questions are thorough and simple, and if you have questions, the TTP team is great at answering them. I completed all the modules and did all the practice questions, and it raised my GRE score substantially.
