(1) First of all, you must listen carefully. At that time, our math teacher liked to write on the blackboard while talking about courseware. There were many books on the blackboard every time, but I didn't think it was necessary to copy them all, or even not. Some people's math books are full of notes, which I think is quite strange, as long as you know these things. And how to understand it depends on your listening carefully. Teachers' thinking takes students into account, and sometimes they are slow. At this time, you should seize the opportunity to understand what he is saying. Remember, you should follow the teacher's thoughts closely. If sometimes you can't understand it too quickly, remember to make it clear after class, either surf the Internet or ask the teacher.

(2) So, mathematics is not just about knowing formulas. You should also understand how these formulas come from, and have more ideas than others. Many people think that this understanding is just that I can put the formula into the question and use it, but it is not. For example, I heard a speech by Professor Luo Boshen of Carnegie Mellon University in the United States, which had a profound impact on me. In class, the professor wrote the formulas for calculating geometric volumes such as cones, cylinders and pyramids on the blackboard and asked us if we had learned them. Of course, we feel that these formulas are already familiar, and there is nothing to do. But when the professor asked us how these formulas were derived, we found that no one could accurately tell the principles of these formulas, such as why the volume in front of the cone is 1/3, why the volume in front of the pyramid is 1/3 and so on.

(3) Be sure to get into the habit of writing extracurricular questions. Experience one semester personally, do not write extracurricular questions, and take the final exam 100. And the questions we brush can't be too simple, just brush a little harder. Of course, this is just a suggestion. It is best to choose according to your actual situation. It's too difficult and will waste a lot of time. If you learn something every day, write your questions there at night. It is very useful.

(4) Thinking training: Thinking is undoubtedly the most important. Keeping up with thinking means that you understand, listen carefully to the teacher's analysis process, follow the teacher's thinking, and develop new methods appropriately. Personally, thinking is the most important. After all, there is a big difference between thinking it out by yourself and pointing it out by the teacher.
