^ Ditto the above advice. You won’t be able to transfer in before enrolling and transferring during your time at UMN is going to be near impossible given the highly selective nature of the program.
So what you CAN do - assuming your heart is set on nursing - is to inform your advisor of your intent to obtain a master’s in nursing and have him/her help you select gen. eds. and a major that compliment and prepare you for this goal. You can also begin to review the possible majors in CFANS and the Masters of nursing pre-reqs to make sure you meet them at some point during your undergraduate years.
Good luck to you.
