Third, in the last few days, there is no need to do problems, read books, and check for leaks.
Fourth, usually do the questions. As for how much to do, it depends.
Finally, I have to remind you that since it is an exam, mentality is very important! A good attitude is the premise of doing well in the exam!
Work hard! Come on!
