Hi,Megan,
These ,Animal Science' courses now availabnle at various colleges and universities are of no use to you whatever if you want to be a vet.
The only way to quailify as a vet is to attend at one of the six university veterinary schools in the UK, and to gain entry to one of those you need A levels at A grades
in Chemistry, Biology and Physics or maths.
Unless you do a crash course in thes eubjects, I think that you have left it too late.
