My friend had an exam but he didn't come because he was sick. Then he needs to pass the exam even he wasn't there. What is the verb or phrase which describes what he needs to do? ("making-up" the missing works here?)
In addition, in Europe, in some of the universities if you didn't come then you have to pay to the university on the missing class and then you have to go with the receipt to the professor of the missed class and you have to represent the topic that you missed and show him that you studied by yourself, and he asks question about the topic in order to ensure that this student controls in the topic. Is it called "making up" classes or it is something else?
