This guide covers 8 undergraduate bioscience programmes at Imperial College London — ranked #2 in the world (QS 2026) and #6 globally for Life Sciences & Medicine. It is written specifically for students applying with A-levels from international schools for 2026–27 entry.
Imperial's bioscience programmes span three faculties: the School of Medicine, the Faculty of Natural Sciences, and the Faculty of Engineering. All programmes share a 15 January UCAS deadline and most require a strong personal statement. Key differentiators: Molecular Bioengineering requires an interview; five programmes require the ESAT admissions test; and all programmes require IELTS 7.0 for international students.

Which Programme Suits You?
Find your best fit based on your interests
"I love human biology and want to understand disease"
→ Medical Biosciences
Also consider: Biochemistry
"I enjoy engineering and want to build medical tools"
→ Molecular Bioengineering
Also consider: Biotechnology
"I want to change medicine without being a doctor"
→ Medical Science & Innovation
Also consider: Medical Biosciences
"I'm fascinated by bacteria, viruses and infection"

Tip: Apply for what genuinely interests you. Passion shows in your personal statement and is central to Imperial's selection process. Do not apply for both BSc and MSci of the same course — you can switch internally in Year 1. Do not apply for both Biological Sciences and Microbiology — they share a stream and it wastes a UCAS choice.

Important: Website minimums understate real competition. 47% of Bioengineering entrants achieved A*A*A* or higher — vs the stated A*AA minimum. For Biochemistry, A*AA is the practical target for overseas applicants, not AAA.
ESAT — Engineering & Science Admissions Test
Required for 5 of 8 programmes. Sit only ONCE — only your first score is used.
Format: 3 sections × 27 multiple-choice questions × 40 min each. Scores range 1.0–9.0. Top 10% score above 7.0. 2027 entry: Sitting 1 October 2026 / Sitting 2 January 2027.
No ESAT — 3 Programmes
Medical Biosciences No ESAT
Medical Science & Innovation Interview
Molecular Bioengineering Interview
Molecular Bioengineering uses a shortlisted online interview instead of ESAT. Medical Biosciences has a guaranteed offer policy for predicted AAA — no ESAT is a distinct advantage for borderline applicants. Medical Science & Innovation is a new course with fewer historic applicants; no resits accepted.
IELTS Requirements
All 8 programmes require the higher IELTS band — IELTS Academic only. Valid for 2 years. Must be from a single sitting.
7.0
Overall band
All 8 Imperial bioscience programmes require a minimum overall IELTS Academic score of 7.0, with a minimum 6.5 in every individual section (Reading, Writing, Listening, Speaking). There are no exemptions — this is higher than most UK universities. Plan your IELTS test early; scores expire after 2 years and must be from a single sitting.
