U of Michigan college of nursing - Please Help!!!

Hi everyone,
I am currently going to be a sophomore in highschool, and have been thinking about majoring in nursing in college. As I search through the many colleges and their nursing programs, the University of Michigan has really stood out to me and is now my dream school. Now I am wondering what I need to do for the remaining 2 1/2 years of my highschool career before college apps begin to increase my chances of being admitted into Umich’s school of nursing. (Extra curriculars they like to see, test scores I need, classes I should take, etc.)

Thank you so much for your help!!
