1: Don't go in too early, go in later. Because the teacher will read it carefully at first, and when they are tired, they will have no mind to read it carefully. So I won't ask you too difficult questions.

Don't make excuses for yourself when the teacher says something, just nod and say, mm-hmm. So the teacher thinks you have a good attitude.

Read your paper several times, so that you are sure to pass.
