GMAT is designed in a way to punish shortcuts and gimmicks. TTP course and materials are long and tiresome. This course really demands a lot of time, attention and effort from you. This doesn't provide any shortcut. Chapters are long with lengthy exercise. But this is what you are need if you are looking for a big jump in score or want to score in high percentiles. It's very methodical. Builds layers and layers of foundation on top of one after another. And Scott is really excellent to help with your exam/ prep anxiety. TTP helped me score a 100th percentile in Quant and 97th percentile in DI.
