Big help for the basics and overall strategy

Strengths:

Full course is broken up into multiple easy to follow chapters. The self-paced nature makes it super flexible, so you can improve your weaknesses by working on your specific topics of interest. Multiple chapter tests to reinforce learning, which makes it what you're learning almost second nature at the end of it.

I did some self-prep with OG guides for a couple of months, but I kept missing easy questions. Because the GMAT is an adaptive exam, simple mistakes are a killer, as you won't perform at your level. This broke my confidence and made me more anxious. So, I decided to switch things up and opted for a month of TTP.

Because of my technical background, I am used to long proofs and abstractions in math. The TTP DI and Quant courses helped me by introducing me to more practical and concise problem-solving methods that are less error-prone than my usual complicated methods.

Also, the large number of topic-specific questions were so helpful in solidifying those skills, so they became second nature. I still made some of those mistakes, but way less of them. More importantly, using the TTP course gave me my confidence back by reinforcing the fundamentals. This allowed me to have high consistent performance in my mocks, unlike 6 weeks before, where my mock scores were all over the place.
