Similar to when I was in high school (12 multiple-choice questions, 4 fill-in-the-blank questions and 5 big questions), the teacher specially gave us special training on multiple-choice questions (12 questions) and fill-in-the-blank questions (4 questions) in the review of senior three. We do it in class, collect it as soon as the class is over, and never delay 45 minutes. We couldn't finish it at first, so we practiced slowly. So I suggest:

12 multiple-choice questions (3 points) +5 fill-in-the-blank questions (4 points): 50-60 minutes; Four 8-point questions: 60 minutes

Note: There is no need to make choices and fill in the blanks in the exam step by step as usual. The answer can be quickly determined by using special value substitution method, exclusion method and graphic method. Of course, we must not be hasty, because two fill-in-the-blank questions can be worth a big question!
