Hi,
I am sorry to have to disppoint you, but you do not have an earthly chance of getting into a University veterinary school without a science qualification, and the only way of becoming a vet is to go to University and get a degree in veterinary science.
You may be able to study for a qualification in veterinary nursng, and if you go to www.rcvs.org.uk and look up veterinary nursing, you will find what the requirements are for that. Theye are not as stringent as for a vet.
