I'm a Sophmore as well and I pretty much have my entire life planned ahead of me, like clear up until I retire! LOL! I plan on becoming a veternarian and hopefully graduating high school early with an Academic Honors diploma and taking 5 AP classes. I volunteer at a vet hospital. Have for the last three years. If you want to be a vet, you need to start doing something like that NOW! Otherwise, vet schools will probably over look you. Not trying to be mean, but I've went to several vet school open houses for colleges (like Purdue, Univ. of Tenn., Ohio State, Univ. of Illinois) and that is something they highly suggest. THey only except like 100-150 kids into vet school (depends on which college), so openings are far and few inbetween considering there are only 29 colleges in the US that have vet schools. If you do happen to start volunteering at an animal clinic, keep a notebook of everything you see and do. Even if it's just washing surgical utensils. Anything and everything counts!
Oh! And goatgirl132, the EMT/Paramedic field is a great field to go into. My dad's a paramedic. He says its the most rewarding job. There are very sad moments when you are working on someone and they die, but it's the same in the vet field to though.
