A-Level and academic profile
St Andrews requires AAA including Chemistry and Biology. St Mary's Twickenham requires AAA prediction and offer requirements, must include chemistry or biology as well as one of biology/chemistry/physics/maths. Resits only considered in exceptional circumstances. GCSEs: grade 6 minimum in maths, English language, biology and chemistry (or dual award science).. Both demand the same A-Level grade band, so academic prediction is unlikely to differentiate your application between them — provided you meet the required subject combination at each.
Interview formats
Both St Andrews and St Mary's Twickenham use MMI interviews, so the underlying prep approach is the same — practise ethics frameworks, NHS hot-topic answers and (for MMI) structured station responses against a timer. Interview windows: St Andrews interviews in December - March; St Mary's Twickenham in December - March.
What makes each distinctive
St Andrews: Three-year pre-clinical course at St Andrews followed by transfer to a partner medical school for clinical years. SJT not used (was used many years ago, not now or in future). Scottish students face much lower cut-offs than RUK applicants. St Mary's Twickenham: For international students only and new this year - apply directly in addition to your 4 UCAS medical choices, so no harm in giving it a try. The medical school is actively seeking links with international applicants.
