OG (Official Guide) is the official guide to the GMAT test, that is, the textbook prepared by the GMAT question institution, as the most basic review and preparation materials for the GMAT, with high authority and value.

All grammar questions contain all grammar points and questions, as long as you understand these more than 100 questions, I believe that you have absolutely no problem with the grammar part. Therefore, grammar review is a process that requires both quality and quantity, but quality is particularly important.

og grammar I recommend you to brush it 4-5 times. You may think that this amount is a bit outrageous, but in fact, the details and time are different each time. Next, I will introduce to you how to brush the syntax of og at the beginning.

First time: Use! Pencil! Do the questions directly on the book (gently!) ）。

A group of about 16 questions, preferably limited to 20 minutes. This process adjusts itself to each person's level, so remember not to answer one question to another. Depending on how much time you have left before the exam and how much time you have to revise, you can freely determine how long it will take to finish.

After brushing, check the answers and carefully look at the analysis on the og. Even though it's in English, even if you can't read it well, you have to check the dictionary to read it. At that time, the official explanation was much more accurate than that of other netizens, so you must read it carefully.

You will find that you spend a lot more time reading and analyzing the right and wrong questions than doing them, so be patient at this time. And even if you get this question right, you have to read all the options and analysis. The first pass is a process of familiarization and accumulation.

Second pass: Draw the grammatical points of the question.

Wipe off the marks of the first pass completely, and then do the second pass with a pencil. After the first binge, you will find that the grammar points and pitfalls used in the problem are clearly pointed out in the parsing section. In the analysis part, draw the grammar points used in pencil, and then go to the grammar notes to refer to the corresponding grammar points to supplement knowledge.

If you encounter something you can't understand, ask questions in the forum in time, ask Du Niang, and make corresponding additions to your grammar notes. The purpose of the second step is to draw a general picture of the structure of the grammar test in your mind. Then you can do the questions through a third party, and I usually use this aid.
