Chances at uw Madison

I love Madison a lot and want to get in. I have a 1450 sat, however my gpas from freshman and sophomore year are 3.0s, but I got a 3.9 my junior year. I am very concerned about this disparity.
I want to be a pre vet major and I have 1,436 hours at an emergency clinic from the past 2 years and summers. I also work at the la zoo on Sundays every week. I am president of my schools pre med club and part of 2 other clubs throughout my high school consistently.
Any help would be appreciated:)

Keep up the grades. UW will note the improvement and it matters much more than your slow start.

Thank you thats encouraging.
