<p>Hello.
I got accepted into UCI, UCSD, and UCLA. It seems like I'll be attending UCLA.
Do I have to tell UCI and UCSD that I won't be attending their schools?
Thanks.</p>
<p>You don’t have too. But you could “decline” their offer of admission. It might help waitlisted students. If you change your mind, you can always accept it again as long as you do so before June 1st.</p>
