Hi, Danielle,
I am sorry if I seem to be pedanatic, but your first step is to learn how to spell 'VETERINARY' !
You must go to a University veterinary school - that is the only way to become a veterinary surgeon. The veterinary course is one of the most difficult to get into and oe of the most dificult to follow. It is full time for five years, and the degree you obtain at the end of your studies entitles you to become a Member of the Royal College of Veterinary Surgeons,, and then you may work as a vet.
If you look elsewhere on this site you will see details of requirements at O and at A levels.
