It also depends on the school you want to go to all. All veterinary schools got a list of prerequsites you need to take to get in. Some classes like you with calculus and others perfer statistics classes-Colorado University-.

Right now you should start taking as much science classes as you can when you are in high school. Take biology and chemistry classes of every type.And really learn alot of math, dont be like me Im trying to learn the math now because I dropped out of school.

When you hit college get a biology major. And make sure you get all prerequsite classes for your intended vet school. You could do it, if you try your best. Good to know another person is pursiting this career. I seriously wish you the best., I hope you make it.
