Does anyone know what mood helps with Uni?

It depends on the subject when studying, doing homework or doing skills for a class. For instance, inspired for the creative arts such as; painting, writing, photography skills, etc. But when attending class, being on time, taking notes and being in a focused mood is the best. Doing presentations, taking tests/exams, again, focused is the best mood in my experience. I've had several Sims attend Uni and the majority of them all got an A+ average graduating with honors for a Distinguished degree using this method. Hope this is helpful! :)
