UCAS CFG0, three years
UCL describes a three-year BSc whose broad first year leads to a chosen specialism from the second year.

UCL Natural Sciences: a broad first year, then you choose
UCL's Natural Sciences BSc is for students who want to delay specialising. The first year is broad and leads to one of many specialisms from the second year, and Mathematics is required alongside at least one of Biology, Chemistry or Physics. It is a different proposition from a single-science degree, and from the specialist Natural Sciences course at Cambridge.

What UCL asks for in Natural Sciences
Taken from UCL's Natural Sciences BSc course page (a saved copy that UCL labels as possibly not showing recent changes) and read on 31 October 2026. For a normal 2028-entry application, made in 2027, every requirement below is last verified for the previous cycle and may change; UCL's 2028-entry requirements and dates are awaiting publication.
A*AA with Mathematics and a science
The A-level requirement is A*AA, with Mathematics and at least one of Biology, Chemistry and Physics required.
IB 19 points in three Higher Level subjects
Grade 6 in Mathematics and at least one of Biology, Chemistry and Physics, with no higher level score below 5.
A broad first year, then a specialism
UCL says specialisms are chosen from the second year and reflect its interdisciplinary research expertise.
A Study Abroad version
The course is also available with Study Abroad, adding a year in another country.
Official sources
Read on 31 October 2026 on UCL's Natural Sciences BSc course page (a saved copy that UCL labels as possibly not showing recent changes), which describes 2027 entry. UCL's department pages, the fees pages, the contextual-offer details and the 2028-entry values were not read, and the page lists no admissions test or interview so none is stated and are not stated.
The course
Develop a scientific identity before you specialise
UCL says the course is designed to help students develop a scientific identity, with specialisms that reflect its interdisciplinary research strengths and today's global challenges. The specialism is chosen from the second year; some specialisms need particular A-levels and first-year foundation modules, so the first-year choices matter.
Is it the right degree?
Natural Sciences against single-science degrees
The flexibility is the point, and its cost is that some specialisms have their own prerequisites.
Choose Natural Sciences if
you want to keep several sciences open and choose your direction after a year.
Choose UCL Chemistry or Physics if
you already know your science. Avandy's UCL Chemistry and UCL Physics guides cover them.
Compare Imperial's single-science degrees if
you want depth from the start. Avandy's Imperial Chemistry MSci guide records its own rules.
Entry rules
Mathematics plus a science, and a high grade standard
A-level applicants need A*AA with Mathematics and at least one of Biology, Chemistry and Physics, and at least two A-levels from UCL's list of preferred subjects. IB applicants need 19 points in three higher level subjects including a 6 in Mathematics and at least one of Biology, Chemistry and Physics. UCL's page lists no admissions test or interview. This page states no scores.
A decision framework
Three questions before you commit
This is Avandy's own framework, not UCL's.
Do you want to delay specialising?
The specialism is chosen from the second year.
Is Mathematics a strength?
It is required at A level and Higher Level.
Have you checked each specialism's prerequisites?
Some need a particular A-level or first-year foundation modules.
Planning for 2028 entry
Planning for 2028 entry: what carries over and what is awaiting publication
Applying for 2028 entry means applying in 2027, under rules UCL has not yet published for that cycle. Each item below carries one of two labels. Last verified for 2027 entry means UCL published it for the previous cycle and it may change. Awaiting publication for 2028 entry means UCL has not yet published it.
Grades, the subject requirements and the preferred-subject guidance: last verified for 2027 entry
These are the best guide to what to prepare. UCL has not confirmed them for 2028 entry.
The UCAS deadline and the 2028-entry requirements: awaiting publication for 2028 entry
Check UCL's course page for the 2028-entry values when they appear.
What to do now
Confirm the required subjects, read the course structure and plan your preparation around it.
Support
Independent support with course choice and preparation
Avandy provides independent academic and admissions support. It is not affiliated with University College London or any of its colleges or departments. Preparation sits within the Avandy Trinity Advisory Model: a Strategic Admissions Consultant, a PhD-level Academic Mentor and a Subject-specific Tutor, working to the actual requirements of each course. Support here means course-fit advice, subject mentoring and ethical preparation; Avandy gives no scores or probabilities and does not write applications. No outcome is promised.
Questions
Questions applicants ask
What does UCL Natural Sciences BSc require?
A*AA at A level with Mathematics and at least one of Biology, Chemistry and Physics, in UCL's wording for 2027 entry.
What is the IB requirement?
19 points in three higher level subjects including grade 6 in Mathematics and at least one of Biology, Chemistry and Physics.
When do I choose a specialism?
UCL says the first year is broad and leads to one of many specialisms studied from the second year.
Can I study abroad?
UCL says the course is also available with Study Abroad.
Does Avandy state offer scores?
No. This page records UCL's wording for 2027 entry and states no scores or probabilities.
Are these the rules for 2028 entry?
No. They are UCL's wording for the 2027 application cycle. Check the course page again when UCL publishes its 2028-entry requirements.
