In principle, you should answer the questions from beginning to end, because in the design of test questions, it is generally designed in the order of easy first and difficult later. Answering simple and easy-to-do questions first helps to ease the tension and avoid losing points because the questions you can do are not finished. If there are some forgotten knowledge points on the actual answer sheet, you can "jump" over and do the following questions first.
Carefully examine the answer sheet, slowly and steadily.
The simplest topic can be read once, and the general topic should be read at least twice. For most students, the answer time is tight, especially the last two questions take up more time, and many candidates have less time to check. So scores often depend on the first answer. In addition, problems such as solving equations and solving resolution functions should be checked first and then done.
Pay attention to traps when answering math papers.
Pay attention to the requirements in the question when answering questions. How to ask in the question, let's answer. Seeing the whole problem clearly is the primary concern.
