3 months of TTP got me from 535 to 705 GMAT Focus.

Strengths:

TTP structures the course in a way you are building knowledge on top of previously learned topics, reinforcing your memory and strengthening your skills. The example questions throughout the lessons + explanations + large amount of chapter tests separated by difficulty levels all add up to really solid understanding of topics covered. So many times during GMAT mocks I caught myself using skills from lesson 1 without a second thought as it came so naturally to me at that point.

What I love the most about TTP is its error trackers and the analytics capabilities, as well as custom tests. At the end of my test prep after finishing the lecture portion, I heavily utilized all these resources to address my weak areas with fresh set of questions over and over again. I only used 1 course other than TTP but I think TTP's resources are truly distinguished and valuable if you are committed to the goal of certain score for your GMAT.

Would make the product better:

- After repeatedly taking custom tests, you run out of quant and DI questions (especially DI). I happen to have some GMAT books I got for free so I ended up using a lot of those for harder questions + GMAT club.
- Video explanations can feel tedious and slow. I watch most of them 1.25x (non native speaker)
- I think some contents in verbal sections can definitely be shortened and instead introduce more questions. Chapter tests didn't have hard level tests unlike quant sections that had a variety of hard level questions.

I started my GMAT prep in mid October with a different course, and after spending (wasting) about 3 weeks with another cheaper course where I could not see any improvement in my quant, I decided to invest in myself and purchased TTP 6 months in November of 2023. It's important to note that I do not have any quant background, and have always been very strong in verbal/literature areas but I decided to pursue MBA with more technical/quantitative focus, so getting decent GMAT especially quant & data insights seemed a daunting task for me.

Anyway, in the previous course, I kept getting frustrated with myself because even after reading articles and watching videos, I got so many questions wrong. With TTP, things were immediately different. I took notes as advised, took every single question available, watched every video explanation and answers for questions I got wrong. And before you know it, I was meeting the target scores of chapter tests with ease. This gave me confidence to power through the course and study for 3 months while working full time.

Eventually, after 3 moths of religiously sticking to TTP course, I took my first GMAT in early February and got 675. I decided to practice a little more for 3 weeks and ended up with 705 at 99 percentile (equivalent of 750 at old gmat).

One thing to definitely note though is that it requires commitment and time investment, especially if you want to be thorough. I work full time so I spent 2~3 hours per weekday and 8+ hours over the weekend every week including Thanksgiving, Christmas and New Year Holidays.

To be fair, some people might start with much better foundation / quant skills than I did and thus don't have to spend that much time, and that's great! But for those who are weak in quant and are specifically looking to improve that by TTP, I want to flag this isn't "let's cram in 3 weeks" kind of course.

But if you are dedicated and willing to put in the work - it works!
