TTP structured test plan enabled me to go from 620 to 750

Strengths:

TTP is strong in covering all areas of the exam. Most reviews here will say they are best at Quant, and I agree with that claim. In addition, their Reading Comprehension lessons helped me view the section in a new way and overcome a pattern of common mistakes.

Would make the product better:

I have very few points of feedback because the most important elements of the program, the content of the lessons, and the practice problem sets are great. TTP could improve the % complete tracker, which indicates how much of the program you have completed. For some reason there were two different numbers and they were always slightly different, so I wasn't sure which was accurate at a given time.

TTP gave me the fundamental building blocks to approach the test differently and more efficiently than I had before I started with TTP. Before starting with TPP, I would just do random problems sets and problems from the GMAT book. At the time, I didn't understand how much I had to un-learn and re-learn in order to approach problems from a new, improved perspective.

TTP offers countless problem sets that are very high quality and prepared me well for the test. While I can only claim this from my own perspective, I feel like a good portion of the TTP 'Medium' questions were actually borderline 'Hard' by GMAT standards. Because of this, I felt comfortable and capable when difficulty would start to increase on true practice tests. (I don't claim this to be the case! Just an anecdotal pattern I picked up on).

If you are considering the 6-month, Maximum learning option, be prepared to commit yourself to the GMAT process for the long-term. I needed this option as someone who had plateaued in studying on my own and as someone who has testing anxiety. TPP is ultimately what you make of it, but it offers the ideal framework to succeed.
