Solid pricing and a useful product

TTP is a budget friendly option optimal for go getters. While it takes somebody with enough discipline to work their way through the entire course, TTP is a fairly comprehensive option when combined with the free problems available online, especially on GMATClub.

Frankly, I didn't have the discipline or the time to work through everything before I took the exam, but I found the piecemeal portions I went through quite helpful nonetheless. I certainly used many of the strategies TTP taught on the actual GMAT exam.

Far more effective for quant than verbal, as the verbal still has kinks to work out, but the quant alone is likely worth your money. I would recommend TTP to those looking for something cheaper than a class, but more thorough than a book.
