Hi,
Your selection of "O" levels is very impressive, and good results are taken into consideration.
At "A" level Chemistry, Biology and Physics or Maths are, I understnd, essential. The pressure of applicants to the vet schools continues to be very high, and now appears to be partly based on Government instructions to discriminate towards pupild from state school, even with poore results.
However, it does seem that as pressure grows, selection will also depend on other factors such as experience and dedictaion as assessed at interview.
