A semester lasts ***7 days, including 4 days of classes, exams 1 day and 2 days of holidays. How can you attend classes for four weeks after one semester? Either you have the wrong number or there is a bug. Universities in sims 3 have a credit system. You must complete 48 credits before you can graduate. Finally, the university can get 6-36 credits (at most, you can get 18 credits in one semester, and you can choose the credits you get when you register). After the final exam, the system will send your score to you by mobile phone. If you reach 48 credits, the system will hold a graduation ceremony on Sunday. After the ceremony, you will get a degree, and you can add a function. If not, you will get a degree.
