Can I take one a level subject only and still get into foundation year in a UK uni

It is possible to get into a foundation year at a UK university with only one A-level subject, but it will depend on the specific requirements of the university and the subject you are applying for. Some universities may have specific entry requirements for foundation year programs, which may include a minimum number of A-level subjects or specific subjects that you need to have studied.

It is important to check the entry requirements of the particular foundation year program and university you are interested in to determine if you meet their criteria. Additionally, it may be beneficial to contact the university's admissions department to discuss your specific situation and see if they would consider your application with just one A-level subject
