Fill in the blanks for about 30-40 minutes, intermediate questions for about 30 minutes, and difficult questions for about 50 minutes. Try to add questions as soon as possible. Additional questions are generally relatively simple. It's hard to say when. I forgot everything in the college entrance examination, mainly depending on the basic skills, and tried to ensure that the first time was correct. The general 18 question is not difficult, but the last two questions are difficult. If you can't do it, spend your time on the previous inspection. It is also a waste of time to do it without thinking.
