I think I have taken a group of YAs through Uni at least three, or maybe it's four times now. I am up to taking seven Sims at a time. I have them live in the same dorm. They are two separate families, but this time one of the brothers is already married to one of the identical triplet girls. Although his older and younger brother are quickly falling for the other two trips. I'm having a blast. All of them have a GPA of A+, for the first two Terms. I load them down with four Core classes, each so they can be done with it and graduated in three Terms only. I like the challenge of Uni, still. Oh, did I mention the married Sim is also a Global Superstar, Rock Star? So, in between things he still holds (rabbit hole) concerts, photoshoots and acts in bit parts for a major movie. On Sundays, he heads off to the Starlight Accolades in the hopes of garnering yet another trophy for his shelf. He has six so far. Yay. At least it's now for his MUSIC. They just began their third term, too.
Yes, I would say it's still worth it.
@JAL I beg to differ with you. Play is basically the same as in town, inasmuch as you can only control one of your Sims in the household at a time. But I take SEVEN Sims to Uni to live in the same dorm. this allows me to control them. Now, I admit it can be tricky keeping up with the daily tasks but for me it's just a matter of getting my rhythm. In fact, I just learned a new trick I wasn't aware of in pervious go-arounds. I don't have to scroll down all four classes for each Sim to see what homework needs to be done. All I have to do is click on their homework notebook to see what they haven't finished. I like to get their presentation boards and those pesky Term Papers written, well-edited and submitted, too. For my young Rock Star, it's essential he gets ahead of the game, so to speak. In my mind taking two Sims through Uni would be a piece of cake.
