Great for quant foundations, but not to be used by itself.

After reading all of the glowing reviews online (Reddit especially) I really expected to be blown away by TTP. It was pretty good and definitely comprehensive, but there were a fair number of drawbacks to be considered. I consider it a useful tool to supplement your prepwork - if you're only using TTP and no OG materials you will have a bad time in trying to achieve a top-tier quant score imo (see my score for reference lol, still trying for it).

The quant materials are undeniably thorough; if you're a total beginner to quant this course will help you master the foundations. They drill the most basic concepts into you over and over. But the TTP quant questions are incredibly straightforward, even at the hardest difficulty levels, and they won't teach you the common "tricks" that browsing 600-700 level OG questions on here would. It won't teach you any novel test-taking strategies either.

I would recommend TTP if only to use as a foundation for drilling OG questions either here or through Wiley's site. I don't regret the money I spent on it but I'm also a bit confused by all of the rave reviews, as if the course has no flaws.
