What should I pay attention to when I do the science comprehensive examination paper for the first time?

Grasp the time, generally there is not enough time to do the paper, so pick up what you can do, don't delay on another question, find a question with high score,,, hand out the paper first, and probably know what may be difficult. Generally, we don't have time to go back and check when we do the synthesis, so when we skip a question, we should think about whether it is really impossible to solve it, like when we do physics, we should pay attention to the formula. Don't be impetuous when writing papers, do it with a calm mind and look at the questions carefully. When you are nervous, you will easily fall into the trap of the questions. In addition, it is best to do the questions in order, so that you won't lose the questions, and doing physics can also make your thinking coherent.
