Even if the patient is sick because of academic pressure, the school will not take responsibility, because other students under the same pressure are not sick, which shows that the curriculum of the school is in line with the general level of college students' ability.

In addition, if a doctor proves that your brother is ill at school, because he was sent to the hospital on the third day after his illness, the school is responsible, because even if your brother has gone to college and is an adult, the school is still responsible for the emergencies that happened at school. However, if there is no medical certificate to prove that his illness is aggravated by being three days late, you can't ask the school for compensation, because after all, they are still responsible for sending students to the hospital.
