It is enough to do the basic knowledge correctly, that is, to ensure that the multiple-choice questions and fill-in-the-blank questions are correct (except the last question), there will be 6 1 point, and the last two questions will be 54 points, as long as the previous short answers are correct. After checking, you can do two small questions of 1.2 in the last two questions, and you will get extra points if you get it right.
