Highly Recommend TTP

Using only the Manhattan books with what I now realize was casual studying, I got a 680 (Q39 V44) with what you can see is a poor quant score. I ran out of time on quant and was penalized. I thought the GMAT would be relatively simple compared to the CFA, but really it's apples and oranges. It's tempting to white knuckle your way through the quant with tons of algebra and without a calculator, but for most problems, that's just not how it works. I took the test again a few weeks later but there was no improvement. Clearly I needed help with math.

I discovered Target Test Prep through a forum, and I'm happy to endorse the work that Scott, Jeff and the rest of their team have done with the platform. Rather than piecing my way through books, it was much more effective to use an integrated, online interface where you could learn the content and do practice problems. Everyone will advise that you track your progress and keep an error log, and TTP basically does this for you. If you're limited on time, I think you'll see a solid improvement with just the easy/medium problems. I will say, though, that having drilled their hard problems, I consistently got Q48/Q49 in my mocks. The math felt relatively simple — at that point, my inefficiencies were more about test-taking skills and falling for the GMAT's tricks rather than a gap in knowledge.
