A-Level and academic profile
Glasgow 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 Glasgow 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. That said, the specifics differ slightly: Glasgow runs mmi format for dentistry, panel interview for medicine; St Mary's Twickenham runs multiple mini interviews (mmi). Mock practice tailored to each school's exact format is the highest-leverage prep. Interview windows: Glasgow interviews in December - February; St Mary's Twickenham in December - March.
What makes each distinctive
Glasgow: One of the oldest medical schools in the English-speaking world. Personal statement and reference must meet minimum requirements but shortlisting is then driven by UCAT alone. Personal statement reviewed post-interview before offers. 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.
