Don't rush for success, high school is different from junior high school, because it is the concentration place of all wise men. First, you should understand the examples in the textbook, which is the key. When you do the examples thoroughly, you should combine your own learning progress and finish the problems in the math materials. Don't look at the answer yet. Think of the question as a small simulation, look at the answer after you finish it, and sort out the wrong questions in the wrong book.
