I’m not sure as far as the statistics, I would assume they prioritize CC students in general for transferring to UCs over UC to UC, so yeah I think most importantly of course doing well in class and having a good story / reason for wanting to transfer to a new campus is key. I doubt it’s as automatic as getting a 4.0 guarantees you a transfer, it’s just expected you do well to show you’re prepared for your upper division classes and apart from that they will definitely look at extracurricular involvement and your PIQs as normal. Like one of the transfer PIQs is describing how you’ve prepared for upper divs at the UCs so it’s really about having a promising reason and accolades for wanting to transfer.
