As a result of the COVID-19 situation and the disastrous GMAT virtual whiteboard, I took the GRE instead of the GMAT, which I had been using TTP to prep for for 4+ months. With no additional GRE studying, I was able to get a 170 on GRE Quant in my at-home test. I completed TTP start to finish for GMAT. I learned so much and could not recommend the course highly enough. The TTP team is also incredibly responsive -- every time I asked a question, even on a Sunday afternoon, I got a response in minutes. I did every single practice problem and don't regret it!
