When I first send a Sim through university it wasn't extremely difficult for me but it was difficult to understand where my Sim stood in his courses. I get that you can email professors but even when they'd say he doesn't need to do anything else, he'd still wind up with a C or a B in the course. I also think the homework for every class is obnoxious. I totally get the realism but I miss in The Sims 2 University and Sims 3 University Life how you would have your Sim do homework or study and it applies to their overall grade. Not just for one course.
