For mathematics, physical chemistry and other disciplines, do a good job in each scientific research and study ten topics every day. Try to do it yourself first, then pick out the wrong answers, find the corresponding knowledge points in the textbook, and recite them before doing it. Like Chinese, history, politics, etc. Every knowledge point must be memorized. If you want to learn English, you should also know the meaning. You should listen more, practice more and write more, and memorize the key points drawn by the teacher. Don't be shy. Ask the teacher if you don't understand. Recall what you have learned all day before going to bed at night. I hope my answer is of great help to you. If you have any other questions, please leave a message in my message area. I will reply as soon as I see it.
