@NRowe As far as University is concerned, I have to confess I fixate on their grades while ignoring everything else. :/ They don't go to games or to the bar or any clubs, possibly because I was never interested in doing that in RL, but mostly because I'm fixated on skilling up and getting good grades. It's a habit I just can't break! I've learned in the past that I can't get a student thru with more than 2 or 3 classes in one session without stressing myself out - it's a pity they need 12 to finish. I play Vanilla, but I have heard there are mods that can lower the number of classes needed to graduate. With 3 sims and 1 raging werewolf it was just too much for me. :D I deliberately didn't take any of the werewolf skills that would calm her down - I'm trying to decide how she is going to develop as a were.
I'm in the process of finishing a big dorm that has a lot of skill building objects inside in order to maximize my time. The dorms that come with the game are so bare bones you are forced to send your sims out to skill up. I don't have time for that! Another thing to watch for when in Uni, the sims gain weight like crazy. Gym equipment is ok, but I've found Yoga helps the best.
So if you play in a more relaxed style you may enjoy taking 4 sims thru Uni. You have to apply to Uni in advance and then wait a few days to get accepted. The more skills you have the better the classes you are offered. I'd suggest starting Uni on Friday night or early Saturday, that way you'd have time to get their Term Paper or Presentation ready along with that first batch of homework before classes start on Monday. Don't forget to give the Presentation during the week, you won't get credit if it just sits in your inventory.
Oh, and I forgot to say before: NO Big Projects!
