50-point score improvement as a re-taker after 3 weeks using TTP

I switched to TTP after going through the entire EMPOWERgmat course and only seeing an improvement of 20 points on my official GMAT over my initial practice CAT: 640 (Q35, V42) to 660 (Q39, V41). I had always been much stronger in verbal than in quant, but I initially went with Empower with the hope that it would help me boost my scores in both sections. Ultimately, I did improve my quant score by a few points, but I saw no such improvement with verbal. I was deeply disappointed and totally demoralized by the thought of having to take the test again after two months of dedicated and consistent studying, but didn't want to lose my momentum and so I switched to TTP.

I took the diagnostic test, which helped me identify my weakest areas so I could optimize what I spent my time studying/practicing, and spent three weeks drilling, drilling, drilling. I found TTP's ground-up explanations of concepts to be super helpful, and was a little aghast (and grateful) to find myself learning things that hadn't been mentioned once in any of the Empower modules.

After three weeks using TTP, I saw my quant score jump from 39 to 45 on my second official exam. Paired with a verbal score of 42, I scored a 710, surpassing my goal of 700. Needless to say, I was thrilled to see such quick results. My only regret was that I didn't use TTP to begin with. Since I took my second official exam so soon after taking it for the first time, I honestly skimmed, skipped, and jumped around a lot in the TTP curriculum. I can only wonder what I might have scored on the quant section had I put in months of study using TTP and methodically gone through all the chapters and taken all the chapter tests.

For less quant-inclined test takers like me who haven't used or thought about the math concepts tested on the GMAT since high school, I'd highly recommend TTP. It helps you identify where you have the most room for improvement, the chapters very logically build on one another, the chapter tests and review tests force you to retain and solidify your understanding of different topics, and the bookmarking feature makes it really easy to return to sections and questions you may be less familiar with or want to spend extra time reviewing. And although secondary in importance, the site has really good UX.
