Hs senior transfer advice needed

Hey guys, I’m a highschool senior and am currently committed to Seattle U for bio because I got waitlisted from UW Seattle. I’m on the pre-med path and in-state. I really, really wanted to get into UW and while I’m fine with SU, the possibility of transferring from CC is just lingering in my head. I’ll graduate highschool with 45 running start credits and around 6-8 credits from my APs. Would it be doable to do 1 year at CC then transfer to UW even if I didn’t have the full 90 credits/AA? What does the transfer timeline look like? I’ve also heard that the science classes are much easier at SU which is really important bc med schools care about your GPA. Would it be worth it to do the CC route, or should I stick with SU?
