如何看待OG和GWD的差异,谁的解题思路更适合考试.

OG: OG's questions are closest to the questions on real test, since they are selected from retired test questions. The reason to review OG is to reset yourself to OG’s style and degree of difficulty.

GWD: GWD are perfect for practicing pace. But GWD has no standard answers, and some of the answers are still in great debates.

Prep: Prep is the best tool for preparing the real test. It has the actual GMAT questions and it can help your pace. So make sure to save a set of Prep test and do it the day before the test.

My prep steps are OG -> GWD -> OG -> Prep. But everyone is unique.
