I got into colleges like UCLA, GeorgiaTech, Imperial etc., but got waitlisted at Berkeley which was my top choice. Is it worth applying for waitlist?
If I accept a college, say GeorgiaTech, by the deadline, will it be possible for me to change to Berkeley, in case I get in?
You can change your mind up till the day you attend. You can accept the waitlist and accept GT. All colleges realize this might happen.
