Admitted to UW Bothell

Hi!

I’ve been admitted to UW Bothell as a back up.
I have to respond whether I go to UW Bothell within 20days.
However, My ideal university is University of Washington SEATTLE and I’ll get results from UW Seattle in June, I think

Is it possible to enroll to UW Bothell as a back up and cancel it so that I can enroll UW Seattle?

My friend paid the UWB admission fee and then she got into UWS. She emailed to the UWB that she is not going to enroll because she got UWS offer. I think you can do that if you worry.

But they won’t refund you money back anyway
