Fansite Sims Express brings some new info about the Sims 2 University, from the official Spanish site. Tim LeTourneau has also visited Spain on his tour through Europe, and according to Sims Express there is the following to tell:

• There's just one type of university - no public or private universities.
• To get a scolarship, which will help your Sim pay for college, your Sim will need to get good grades during their child or teen stages. Good grades at University might also earn your sim a scolarship.
• When creating a young adult, it's not necessary to add an Adult to the family.
• You can create a family of young adults to play with at University.

Besides that, two artworks are also revealed. You can see them below, and by clicking the thumbnails you'll see them in their full size.
