Our math teacher told us that multiple-choice questions and fill-in-the-blank questions should be finished within 50 minutes, and then if there are big questions, everything else should be almost finished except the final one. Except for the first two big questions, it should be finished in about five minutes, and the rest should be finished in about 10 minutes. There is really no need to finish the meeting carefully first. The most taboo in exams is stuttering on one question. Then be careful. A hundred points should be fine.
