1. The original score refers to the actual score of the students in the final exam, which is the initial score entered into the students' files after automatic calculation by the examination system or manual calculation by the teachers. The original score does not include all kinds of deduction and bonus points. If there are differences in students' grades, the school will let the teacher check the students' answers and add and subtract points manually.

2. The final grade refers to the comprehensive grade calculated according to various factors such as test scores, homework scores and usual performance after the exam. The final grade includes all kinds of addition and subtraction items, such as attendance, course performance, homework completion, test scores and other performance results.
