First of all, analyze the overall situation. Compare the results of this exam horizontally and vertically. Analyze the reasons, analyze what you have done well there, and continue to maintain it in the future. Analysis of the incomplete knowledge there leads to mistakes, such as unclear concepts, weak foundation, calculation errors and carelessness. Sort out mistakes, systematically analyze problems and solve problems. Summarize experiences and lessons, and formulate future goals and efforts.

Build up confidence, show determination and make unremitting efforts. The above is my experience, I hope it will help you.
