The master's thesis will be divided into internal audit and external audit, and the requirements of internal audit will be relatively low. Each college will set aside a certain proportion for external audit and the rest for internal audit. The so-called internal audit is internal audit. The papers are reviewed by teachers in our college, not by the experimental group. There will be three teachers to grade. Of course, the higher the score, the better. As long as one is below 80, there will be a second review. After reading it, there will be comments, which need to be revised according to the comments, and replies are allowed after revision. Generally speaking, as long as the internal audit workload is enough, as long as you are good at writing and revising papers, you can pass even if it is not the first time for you to do it.
