Excellent GRE prep

Target Test Prep is the best choice for self-serve GRE prep. I found the interactive course and structured pace made studying much easier than typical books. The difficulty levels on questions ensure that concepts are repeatedly drilled, and I found the actual GRE easier than most of the Medium level questions.

The course helped me most for Quant but the verbal definition lists also contain most of the same words found across study materials. I would definitely recommend to anyone looking for a flexible study method though self-motivation is needed as you will only get out what you put in.
