How to become a veterinarian?

In Australia, the process is described here:

Basically, you need to do a vet degree, which in Australia is about 5 years, then get registered to practice as one.

You can go straight into vet science though; you don't need to do another degree first. The advice you read could have been for the USA or UK, which have different programs.

The cutoff for Vet Science is quite high- you need an ATAR of 95+ in most cases.

For more information, you can contact the AVA, or universities that have vet science degrees. Also it's worth going to university open days to find out more about the process.

I changed my major in November. I started out in veterinary medicine. Go to a four year school that offers veterinary medicine as a major. Then when you're done, you apply to veterinary school. But you have to have really good grades because vet school is really competitive and prestigious. Take a lot of biology, math, chemistry, and physics in high school. Well, just like you said. Since math and science are your favorite subjects, you'll have no problem. I don't know how they do it in Australia, but that's how we do it in the states.

Look around at colleges and see which ones offer what.
