So you have no undergrad and then vet school?
Here in the US, we graduate high school after 12th grade, at age 18. Then we go to undergraduate college for general studies, along with some specialization. Unlike many other graduate programs, vet school does not require a bachelor's degree, just core biology classes. So some people go to vet school after only two or three years of college. Others stay all four to get their bachelors. Then vet school is four years, two-three of classroom and one-two of clinical. Additional specialization or residency is recommended, but not required.
