During the exam, the students are doing the questions carefully and checking carefully after finishing the papers. But some problems can't be found. I think these wrong questions can't be found out because you understand the problem like this, but the wrong way leads to these wrong questions.
After the exam, most students will compare their answers in the exam with others ... I think this is wrong. You can do something useful during this time. Even if you find a wrong problem, you can't correct it. Not only that, but it will also bring more pressure to your next exam. Instead of wasting time here, take out your book and review it. Maybe in a few minutes, you will know.
After the exam, I realized that real gold is not afraid of fire. As long as you study hard, you are not afraid of exams. The exam is actually a test of how you learned this semester, but a summary ... Some students think the exam is a life-and-death battle. If you win, you will be praised by your boss-that is, by your parents or teachers. If you lose the war, you will be criticized by your boss.
No matter how many "wars" I will experience in the future, I will take it easy and win!
