College of Nursing

Sooo I was finally accepted into utk just last Friday after waiting for a little over 2 months after applying. My first choice major is nursing, however my acceptance letter said that I am currently accepted into my second choice major, and that my application into my first choice major, the college of nursing, is currently under review in that department. I’m simply wondering, is there anything I can do to increase my odds of getting into the program? And how long should I expect to wait for a decision to be made? Just for reference, I’m a guy, my unweighted gpa is a 3.75, my act super score is a 28, I got both of my letters of recommendation from nursing teachers at my high school, and I’ve done all the essays and the personal statement.
