1. Understand the school rules: First, understand the school rules and policies, including the provisions on failing courses and make-up exams. Knowing the school rules can help you know what to do next.

2. Ask for help: contact the academic affairs department or academic consultant of the school to seek their help and advice. They can guide you on the next steps and possible solutions.

3. Re-evaluate learning methods: reflect on your own learning methods and strategies and find ways to improve them. You can discuss with your tutor or classmates and seek their advice and experience sharing.

4. Explore other options: If you find that you can't pass the make-up exam, you can consider other options, such as retaking courses, changing majors or adjusting your study plan. Discuss these options with the school's academic adviser and find the solution that suits you best.

5. Keep a positive attitude: You may feel depressed and disappointed when you fail and make-up exams, but it is very important to keep a positive attitude. I believe that I can learn from failure and strive to improve my study methods and grades.

6. Complaints: Relatively speaking, complaints are the most direct and effective way for international students to solve the problem of failing courses. Through the appeal, international students can get opportunities such as make-up exams and grading, which can help international students solve their academic problems more directly.

Remember that everyone will face challenges and difficulties. What matters is how to deal with and overcome them. With the support of the school and our own efforts, we can find a solution to the problem and move on.
