All the grades of the semester you applied for exemption. For example, you apply for exemption from the exam next semester in your junior year. At that time, if you haven't started the final exam of your junior year or the final exam results haven't come out, it depends on all your grades from freshman to junior year. If the final exam results of your junior year had already come out, then you should look at all the results of your freshman to junior year. Generally, you apply for exemption in June, and only look at the results of freshmen and juniors; If it is September, it depends on all the achievements in the past three years.
