First choose multiple-choice questions, then fill in the blanks, then calculate the questions, then apply for the questions (the bigger the questions or the higher the scores, the later), and finally conclude the most difficult questions.
If you choose to fill in the blanks, you can put a little difficulty in the last one or two. In short, the score of the question should not be too high, which is not good for students' self-confidence.
Hope to adopt!
