1, a firm grasp of basic knowledge: If you want to improve your math scores, you must do your homework every day, just like an open-book exam. Only by completing the open-book exam every day can your grades be gradually improved.

2. Prepare the wrong question book: occasionally do the questions in the wrong question book, and constantly strengthen them repeatedly, because these questions are all blind areas of thinking. Go over the wrong questions before the exam to ensure that all the wrong questions will be done. If you persist for a long time, your grades will definitely improve.
