I love TTP!

TTP was a god send. I was really nervous taking the GMAT and only wanted to take it once so I put my all into studying (studied for about 2 months, 4-6 hours each day). I was also working at the time. Everything with TTP was incredibly helpful, well laid out, and easy to understand. I could take it at my own pace and had everything mapped out for me. seeing my analytics also helped me understand where I normally make mistakes.

The staff answered my questions quickly and politely regardless of how many dumb questions I asked. Would also recommend their verbal section (which is still in beta testing). It was invaluable for me in sentence correction.

Couldn't have gotten my 760 without TTP verbal / quant.
