1. Buy a book that integrates the essentials of primary school knowledge and make more than a dozen books every day (every week). Parents will take the answer, judge it immediately after you finish it, correct your mistakes after you finish it, practice the same type of questions several times, and you can write your own questions; I won't do it. I can ask anyone.
After finishing this week (month), practice the wrong questions this week (month) again, and practice again and again. Just before the midterm (before the big exam), I made a set of comprehensive papers, and I failed ... (I suggest buying more sets of practice papers, starting with the simplest ones-grades 3 and 4)
2. Ask for a tutor (there is nothing to be embarrassed about asking for a tutor. If not, please be responsible and tell you patiently)
3. Buy books that are all answered by books of all grades. There should be a way up there. First, cover the method and do it independently. If you can't draw pictures or list, just do examples and then do exercises (I suggest you do them every day! )
Since new knowledge is based on old knowledge, we should practice from the most basic questions. There are not many points in mathematics. As long as you listen carefully and do it carefully, you'd better draw pictures when you do the problem. It's not that hard. You can learn math well in other subjects, and there is no problem for sure! I believe you! )
This is all my own play, original! If you are satisfied, please choose a satisfactory answer, thank you!
