It's best to get it done one month before the exam.
Then you have to do some simulation questions, otherwise the thinking mode of the real questions will affect you. Because I have done it several times, I have all the basic ideas.
So at this time, you should do a set of simulation questions every few days to practice your hands, because you must have never seen the questions in the examination room.
Pay attention to the time of the card during this time! ! ! Don't do it casually, adjust the biological clock strictly according to the time period of the exam.
Mathematics, two days without doing problems, how many people suffer from it year after year. Don't think that reviewing is enough. You just read and don't do it in the last week. You must insist on making several sets of papers these days. Trust me, come on! ! !
Good luck!
