@Bettyboop55 I always go for two weeks at University. In the first week my Sims can build their grades up and then the second week is easier so I always get guaranteed passes during exams. Doing just one week at a time would mean that my Sims grades would reset every time I send them back there. University is actually really easy if you can get set up in advanced.
Throwing parties is also a good way to get some extra food as guests usually bring stuff of their own so that saves time having to have someone cook food
