Generally, it takes about half an hour to browse the multiple-choice questions first, and each question should not exceed 5 minutes. If you can't figure it out, leave it blank, especially when you can do it but can't think of the answer. It will be better to go back and do it again. But don't forget to do it. You can write the remaining questions on a piece of paper so as not to forget them. It is best to fill in the blanks within 45 minutes. The rest of the time is to do the big questions in order.
