sims still has to work even though there enrolled at the university

seen that this is an old post lol but i thought it was a problem at first too.. i just made it work with my sim. the uni classes really don't do much practically but i felt like my sim was just the type to earn herself a degree. working towards a physics degree while in the astronaut career. i had to figure out a balance. sometimes i have to make my sim skip classes and instead study a ton for the class at home later (which i have found actually maintains a good grade!), sometimes i have to use up my sim's work vacation days. i also gave a very light load of 2 classes every term. it makes the progress towards to degree slower but if you want to maintain a career and classes at the same time you have to sacrifice some things.
