If you can't rebuild, you need to pay tuition to rebuild.

According to the experience of previous years, it is generally easy to rebuild.

It is better to study hard and review carefully before the exam, so as not to fail or even retake the exam.

If you fail a course in the college exam (generally required), you will take it again in the next academic year. Re-taking the exam is called re-taking. Most colleges and universities adopt this strategy: when a student fails in many subjects in the final exam, he will be given a chance to make up the exam in the first week of next semester. If students pass the failed subjects in the make-up exam, they don't need to retake the exam, but if more than a certain number of subjects fail, they must retake these courses. Or four years later, there are still subjects that have not passed, and they need to retake the exam before graduation and pass the exam before graduation. Maintenance needs to pay a certain repair fee.
