A-Level and academic profile
Aberdeen requires AAA including Chemistry and Biology/Physics/Mathematics. 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 Aberdeen 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: Aberdeen interviews in December - March; St Mary's Twickenham in December - March.
