1. Ask the teacher or school to make-up exams for you: Generally speaking, the school will arrange make-up exams, and students can make-up exams at the time and place specified by the school to get the course results again.
2. Undertake make-up classes: If the school does not arrange make-up exam opportunities, students can undertake make-up classes by themselves, absorb course knowledge by participating in make-up classes, familiarize themselves with the exam syllabus, and improve their exam results.
3. Ask for forgiveness: If students can't take make-up exams or make up classes by themselves, they can ask the teacher for forgiveness, explain the situation and ask the teacher to lower their grades.
