Before reviewing, look at what the exam outline specifically tests, which are important and which are secondary, so that you know what you are doing.
When reviewing, it is best to finish reading the book first, so that you can understand all the main contents in your heart and have a general framework in your heart.
Then, it's important that you start to focus on your outline. Only your own outline is valid, others can only refer to it, and your own list can help you master the knowledge structure of the whole book.
When making an outline, it is important to look at the table of contents in front of the textbook and the subheadings of each lesson. Those are highly generalized words that can help you understand what this lesson is mainly about.
After the outline is listed, you will basically master it. At this time, you will have nothing to look through the books. All the knowledge points are in the book. As long as you look at the table of contents in front of the book, you can see the content corresponding to that category in your mind, and you can basically master it all.
If you have time, just do it as above, and it will be finished in 3 days. If you have nothing to do, take out the outline and read it yourself every day.
Finally, I wish you good grades in the exam.
