Best tool out there for GMAT Prep. A must have.

Strengths:

Structured to perfection, UX is greatly designed to keep you grounded and on track, ensuring you did everything you could to prepare. I loved the frequent topic reviews, truly helps you build your ability to focus and answer questions correctly with a good pace.

Would make the product better:

I found some of the verbal sections repetitive. I'd have loved to see some comparison across questions types (i.e. matrix style showing how typical errors show across question types). Nevertheless, the practicing tool was great. I scored a perfect 90 as a non native english speaker.

A must have product at an excellent price. I don't believe it's worth it having an expensive private tutor. I believe getting a great GMAT score is about learning how to focus, and the TTP is an excellent tool for practicing and improving that skill. I initially rushed through the sections and did not get the score I knew I could get (only improved from 690 to 710). I decided to reset the schedule and follow the pace suggested by TTP. By the time I could re-take the exam, I had to adapt to the FOCUS format, scoring a 695. I found TTP to be an excellent tool for both versions of the exam. Can genuinely say this having taken the exam by studying from GMAT books (useless) and YouTube videos (helpful to understand the logic for some problems, but it's not enough to build the pace you need to do great on exam day). During that time I felt like I could solve any problem, but still underperformed on exam day.
