From 435 to 695 thanks to TTP

Strengths:

The theoretical material is very thorough and well-structured;
Many questions to practice;
Topic-wise approach: first they teach you the theoretical material, then they teach you to apply it;
Friendly team.

Would make the product better:

Just one thing: while I was preparing, the course was updated a couple of times (new quant material was added), but the new topics were not reflected in the GMAT equation guide (the TTP's pdf summary for quant)

I used exclusively TTP for my preparation; I also bought the OG, but did their problems only after completing the TTP course and did not even finish the question bank.

I am not a fan of blindly solving tons of problems - this simply does not work for me. So for my preparation, I was looking for a course which would, most importantly, teach me all the necessary theoretical material. With TTP and their topic-based approach it was a perfect match.

TTP offers you thorough, comprehensive and well-structured contents. Moreover, you do not have to worry about systemizing the preparation on your own - TTP took care of it, so you can completely focus on studying the topics and practicing the problems.

Moreover, I liked the strategies and tips that TTP teaches you: from prioritizing accuracy (not speed!) to not giving up on problems until you find the solution yourself.

I would like to specifically thank the TTP for my quant score improvement: it went from 61 to 86, which is huge for me, a person who is not naturally good at quant stuff.

Overall: totally recommended!
