Comprehensive and builds mastery

Strengths:

I personally found the quantitative section of the product to be its greatest asset. While I was familiar with many of the topics on the quantitative section, the continual focus on reviewing past topics and comprehensive list of questions was exactly what I was looking for and allowed me to develop mastery in the topics.

Would make the product better:

While quant lessons are followed by sporadic tests that continue to test your mastery of previous topics, an aspect that I found helpful, I would have loved to see that aspect implemented across verbal and DI as well.

While the course is comprehensive and indeed lengthy, TTP is what you make of it. In verbal, I was running on a short timeline but needed the basics so focused exclusively on question sets and their key concept highlights, cutting out most of the examples in teaching. For quant, I was familiar with much of the content, so dedicated a significant amount of time learning and understanding their question sets. I personally went into TTP after taking the GMAT once, so had an idea on where I needed to improve and consequently was able to extract exactly what I needed from the course to succeed and was able to do just that.
