When I was in class in Shanghai, the teacher suggested that the preparation time for GMAT should be controlled at about 45 days, not more than 3 months, except for the time to consolidate the English foundation.

GMAT review materials are mainly as follows: OG 12 (GMAT review-official guide [12 version])-divided into three volumes: comprehensive edition, language volume and mathematics volume; Daquan-divided into logic Daquan, reading Daquan and grammar Daquan. Without mathematics, the grammar encyclopedia includes OG 12 questions. Perp-divided into old PREP and new PREP(PREP08). PREP has a question bank (that is, the word version of PREP questions we usually do), and we can also conduct a model test in Xianghai. Their student group has PREP model test software. There are many overlaps between gwd-gwd-gwd encyclopedia. Then combined with Chen Wenbin's "GMAT Chinese Test Guide"

Followed by other vocabulary grammar reference books, the New Oriental Red Book series. Core vocabulary, Bai Yong grammar, GMAT reading comprehension, Yang Peng long sentences and internal handouts for GMAT super training in Xianghai.
