1 The most important thing in learning mathematics is to overcome the fear of difficulties. One of the main reasons why most liberal arts students are not good at math is that they are afraid to start when they see a slightly complicated problem. In fact, if you try to do it, you will find that the so-called problem is not difficult. We can give up as much as possible, because it consumes energy and most people can't do it, so don't worry.
It is very useful to set up your own mistake book. It is very useful to extract every wrong question and read it regularly. You can even just do the wrong questions in the book before the exam. Of course, you can't see the answer until you finish it.
Learn the skills of exams. Fill in the blanks and grasp the time. If you spend 3 minutes on a question, you should skip the topic you have to do first. If you want to make a big problem, you must be brave in research and write as much as you want.
This is all my personal experience, I hope I can help you.
