Colleges are free to accept or not accept credits from other schools just as they are free to accept or not accept certain AP/IB scores for credit. And you can choose to transfer to the school or not. Get the facts and make your choice.
A million years ago when I transferred to UPenn they would not accept a Bio credit I had…but I decided the school was great in every other respect so I went anyway and took the required science courses there. Despite my annoyance, it is a trade-off I’d make again (and again and again) without blinking an eye.
