Best Quant Course Available

Took me from 35Q to 50Q (mock exam) and 48Q (actual exam) . The course does take a long time. I would say it took me ~300 hours from start to finish (including all lessons and quizzes). However, going through the entire course gives you all the tools you need to answer every quant question that might be thrown at you. The lessons are extremely detailed but easy to understand and the quizzes build on and reinforce your understanding from previous sections.

My only criticism is that the hardest problems in TTP are not really representative of the hardest problems in OG or the actual exam, but getting 700-800 questions correct is equal parts knowledge, skill, and luck.
