TTP is Great for Foundations (Especially on the Quant Side)

Strengths:

Quant foundations

Would make the product better:

Verbal explanations can be improved

TTP is a great resource to use for GMAT prep. Would recommend to supplement this with official questions and videos from the GMATNinja verbal and DI series

Great material to go through for quant related topics, lots of questions, incredible depth of materials and explanations. Some questions in the material are also slightly harder than the actual GMAT which helps you prepare well for any unexpected hard questions on the actual test.

The verbal section dives a bit too deep into question types too quickly, and I feel there is opportunity to add material that helps students holistically identify traps and choose between the final 2 (most confusing) answer choices. It's useful to start off with TTP for a topic like this, and then supplement with other resources if you feel your score is plateauing
