Hi
I'm a successful Vet Applicant of this year
Got 3 offers.... so I know my way around the admissions process some what
First thing is what do the vet schools want: entry requirements
Bristol - Chemistry, Biology and one other
academic subject
http://www.bristol.ac.uk/vetscience/undergraduate/bvsc/requirements.htmlCambridge - Chemistry and then two of: Biology, Physics and Maths
http://www.study.cam.ac.uk/undergraduate/courses/vetmed/Edinburgh -Chemistry, Biology and then an approved subject (see their link)
http://www.ed.ac.uk/schools-departments/vet/studying/uk-eu-school-leavers/entry-requirementsGlasgow - Chemistry, Biology and another
academic subject
http://www.gla.ac.uk/undergraduate/degrees/veterinarymedicine/Liverpool - Chemistry and Biology and then any other subject
http://www.liv.ac.uk/study/undergraduate/courses/veterinary-science-bvsc/entry-requirements/Nottingham - Chemistry, Biology and then any other subject
http://www.nottingham.ac.uk/vet/prospectivestudents/undergraduate/admissions.aspxRVC (London) - Chemistry, Biology and a third subject
http://www.rvc.ac.uk/Undergraduate/BVetMed/EntryReqs.cfm#a2So as you can see Chemistry and Biology are a must, which you have - so far so good
However, photography and media studies are not (unfortunately) considered academic subjects. One of them would be fine as a 4th AS subject however one of Maths or Physics would be strongly advised. With Vet Med being the third most competitive course (I believe don't quote me on it) you need to pick subjects which won't count against you.
If you decide not to apply for the "normal" 5 year course, you might try your hand at the Gateway courses or similar that some of the vet schools run. Be warned though they are extremely competitive as there are as few as 5 places on each course.
Work experience wise you need at the absolute (and I really mean absolute) minimum is 6 weeks work experience between now and when you apply. It needs to cover the basics of: 2 weeks Large Animal practice, 2 weeks Small Animal practice, at least a week on a dairy farm, at least a week of equine and then very helpful additions are; horse vets, pigs, poultry, kennel and lambing (if you can definitely do lambing.)
If you want any more advice or a second opinion, go to the
Vet Med area
Peace
