It's time to start classes-you can get grades quickly in junior high school. Suggestion: The first round of review is very important and is the foundation. The goal of the first round is to firmly understand and master the main knowledge points in the book, especially the typical examples, understand and cooperate with a certain number of questions, consolidate and review the old and learn new. In the second round, by doing a lot of questions repeatedly, I master the knowledge of books skillfully, and draw inferences from others to improve the stage. In the third round, check for leaks and fill gaps, and return to the original.
