Sending three sims in same household to university?

I just sent my twins to uni together. Not sure if this is the right way to do it, but I had them both apply for scholarships and uni, then check on the computer to see the results. When the first one got accepted, she chose Foxbury and the Tidal Tower accommodation. Immediately after she had moved in, I switched back to my original household and got the 2nd twin to do the same.

Presumably you can keep on doing that for however many sims you want to take.
