Hi, Amanda,
You must have Chemistry and Biology, if possible Physics ( or Natural Philosophy as it is called in sme parts of Scotland!) or Maths, and whatever else you think you can manage - e.g.Geography, a foreign language, English.
You must also get some work experience with animals - kennels, stables, farm and veterinary practice.
For up-to-date information write to the Admissions Secretaries at Glasgow Univeristy Veterinary School, Bearsden Road, Bearsden G61 or the Royal (Dick) School of Veterinary Studies, School Office, Summerhall, Edinburgh, EH19 1QH and ask what their entry requirements are.
