thanks. so SaraMk, I can keep putting my playable teens one by one into the dorms until all of them are in?
Do I have to assign a room for each one before I back out to neighborhood/university view and add the next one?
Emma, If I decide to put them in a household (of up to '8') all at once do I have to give the household a name or will the game choose a last name from one of them?
If you use "send sims to college" from the main neighborhood, it will group the teens together but will not check for scholarships if you haven't done that already. If you group them together in the main hood, it will create one "family group" in the university neighborhood which you can just move into a dorm.
_Or, individually in each house in the hood, have each teen call up the college and move to university. When you go to the university neighborhood screen, you will see each sim by themself in the bin. Pick one and move into a dorm. As soon as you get into the dorm, immediately save and go back out to the neighborhood screen. Pick a second sim to move into the dorm and "merge households" when prompted. You will not go into the lot but will stay in the neighborhood screen when this happens. Keep adding your playable sims, up to 8 or however many your system can handle. Remember that in larger dorms that will contain nonplayable sims, your system resources are still used with the non-playable sims. Even though my system exceeds specs for the game, large dorms really bog down on my computer (community lots in the main hood with the same number of sims don't seem to have the same problem that the dorms do).
If you put them together as a group in the main hood, you can pick a "house" name for the group. If you add them one by one, the first sim added gives their last name to the lot - but don't worry that's just what the lot is called, all your sims retain their own names.
After you've gotten all your sims into the dorm (regardless of what method they choose) it's usually a good idea to assign a dorm door to them. They can lock it for privacy. It's not imperative. I played several dorms before I found out about assigning and locking the doors - it doesn't hurt anything if you don't do it but it can be a big help if you do.
