Great for people not confident in their quant abilities

TTP's quant section did an excellent job of explaining the logic for each question through text and video, and the function for asking questions via chat is helpful to get clarifications. Using the course was much more effective than relying on the GMAT official handbook. I did a few chapters of that but it's hard to bookmark questions and track accuracy.

Highly appreciate the test design. The chapter tests are effective for focused practicing. The review tests are able to help me review concepts across topics and solidify my overall understanding. At first I thought the number of practice tests was a bit excessive, but I observed marked improvement in my quant abilities, so I am grateful for all the practice.

The sentence correction exercises and explanations are helpful too. My reading comprehension was already very good, so I can't comment on the effectiveness of that portion.

Overall, strongly recommend this course!
