1, gmat grammar exam review, the most important and classic gmat grammar book is of course OG, which is a must for everyone who takes the exam. Because this is the authoritative explanation given by ETS officials. According to everyone's specific situation, the number of times you need to watch is different. But generally speaking, there should be at least two or three times.

Because some explanations of OG are very difficult, you can't understand them once. It's not too much to watch it seven or eight times. Remember that practicing OG is not to emphasize the number of times, but to master the thinking of the problem.

2.Prep is the closest question to the real question. The most appropriate way to understand the difficulty of the exam is to preview and crack the grammar. The cracked version of prep contains more than 300 questions, covering almost all the mistakes in grammar.

Among them, prepgmat grammar notes are detailed explanations compiled by many predecessors in the forum according to Prep grammar topics, including topics, option analysis, test sites, expanding knowledge points and so on. Personally, I think this is a necessary gmat grammar review material.
