There are many cases of suspension of classes in universities, and only when the conditions for suspension are met can classes be suspended normally. Suspension from school must be carefully considered. The time and frequency of suspension are limited. You have to fill in the application form according to the regulations, and you can't leave school until it is approved by the relevant department of the school. Students should temporarily leave the campus to treat diseases, and the treatment time should exceed one-third of a semester. Then it is necessary to be diagnosed by the regular medical department and issue a certificate, and take the certificate to the relevant department to apply for suspension. There are also schools that think that students have to drop out of school because of illness, and this kind of suspension is also necessary.
