Dry area is the common name of area A, and water area is the common name of area B. The Ministry of Education stipulates that public courses should be marked by the province where the university is reported, and professional courses should be marked by the university reported. Drought means that there is no moisture, the marking is strict, and water means that there is moisture and the marking is loose. The teacher has the final say on which questions are graded by the teacher. For example, if you score 20 points on an essay question, you can get 15 in area A and 18 in area B, which is reasonable.
