Calgrant School Change for Waitlisted Colleges

I am still new to the Calgrant and I don’t know when the deadline to change school. I am still waiting for the colleges that have waitlisted me. The college I put for the “School of Attendance” is the school I have been WAITLISTED at. Should I wait after the waitlist result released next month to change school? I want to see the result before changing school of attendance. When is the deadline of the school change? Is it impossible to change next month or should I change now? Won’t the amount of aid receive be affected? I don’t want the financial aid to be sent to another school that I am not attending if it is too late to change school or after the deadline. Thank you.
