Generally, for veterinary programmes, biology is a mandatory A level subject, and mathematics is also highly recommended. Other science subjects such as physics, chemistry, biology, or zoology can be useful, but may not be essential. Some programmes may accept applicants with A levels in other non-science subjects, provided they meet certain criteria and have a strong academic record.
It's important to carefully check the entry requirements for the veterinary programmes you are interested in, as they can vary between universities. Some universities may have more flexible requirements and may allow applicants with a variety of A level subjects, while others may be more specific and require chemistry or other science subjects.
If the veterinary programme you are interested in requires chemistry at A level, but you do not have it, you may have the option to take an additional chemistry course or module at a college or university level, either before or during your veterinary degree, in order to meet the entry requirements.
It's recommended to contact the admissions departments of the veterinary programmes you are interested in and inquire about their specific requirements and whether you can fulfill them without having done chemistry at A level.
