There are no parent-teacher conferences in universities, unless you make a big mistake and have to be punished, you can tell your parents. Otherwise, who has time to inform their parents about everything? Um, 10 days? Is it too long? It's not easy to give such a long holiday, is it? You must call in sick. . . . Or simply ask for leave, just cut class 10 days, plus two weekends before and after, and six days in cut class. As long as there are no special activities in the school, the class teachers and cadres agree not to tell them. In college, I don't think anyone will ask such a thing. You are absent except for the roll call in class. But this is not good. Nothing special, just don't.
