Rebuild the original low-scoring subjects, strive for more than 80 points, and explain the situation to the teacher immediately after the exam, so that his old man can be merciful and use it first, but his grades still depend on his own efforts. And don't be afraid to spend money. A degree certificate is very important. Come on, brother, my classmate spent 800 yuan on three courses, played all day before the exam, and scored 30-40 points, so I remind you, if you want to get something for nothing, just keep the money for something good online.
