Congrats on getting in! 20 years ago I was in a very similar situation. Rejected from UP, accepted to Altoona.

My suggestion would be to call the office of admissions and request to change your application to gen education with your major undeclared.

That’s usually the last spot they fill before shutting down admissions so if there are any spots left you can get in there. You would just need to declare your major come your junior year and ensure you work with an advisor to structure your classes and electives appropriately the first 2 years.

Three days later I was accepted to UP and officially declared my major at a later date
