I was already accepted to College of engineering at Madison as a senior in high school but decided not to attend
Seems likely you will be accepted as a transfer student and can succeed. Remember you get admitted to the university as a whole, regardless of your intended major. Be sure you have a solid foundation in your STEM classes to be prepared for engineering at UW.
