CSU Vet Start Program?

I know this program is extremely competitive (only 5 students- yeep!). So far im only a sophomore, but I’ve wanted to be a vet since I was 7. I have an ehh gpa (3.5/3.6, hoping for a 4.0 second semester!) But as a sophomore (and as a junior and senior) , Im taking the most difficult courses my school has to offer (including an AP and IB course). Can ACT/ SAT 2 scores bring it up? Also, does this program shave off any time? Does this impact my chances of being accepted into a residency program?
