Great for Quant

Strengths:

The Quant learning path is exceptional and there are ton of questions available to get up to speed. There are different difficulty level questions available so that a student at any current quant level can use it to get to Q50 or Q51.

The custom tests option is also quite good to test out few specific concepts.

Would make the product better:

I've expected the verbal content to be on par with the Quant content when I signed up for TTP after reading about it on Reddit. It is also quite an expensive subscription for people outside US.

If you are struggling with Quant, it is a great resource to get to Q50+. The learning path, the question bank and the analytics will help you a lot.

However, the verbal questions are unnecessarily hard, and quite low in number.

The SC questions, particularly, are very different from what you would get in GMAT. In GMAT, the SC questions are amalgamation of all the different SC concepts. In TTP, the SC question bank has questions that test only a particular concept of SC. Knowing about the concept prior to answering the question is not going to be the case with GMAT SC. You wouldn't know before answering the SC question, what concept is being tested and one of the crucial aspect of GMAT SC is being able to identify markers for the questions.
