Entry Requirements
This page shows the standard entry requirements for this course. A PDF detailing any variations between Colleges (some may ask for an A* in a particular subject for example) will be published here in April 2023.
Typical offers require
A Level: A*A*A
IB: 40-42 points, with 776 at Higher Level
Other qualifications: See Entrance requirements.
Subject requirements
'Science/mathematics subjects' refers to Biology, Chemistry, Physics, Mathematics and Further Mathematics. It does not include Psychology.
- All Colleges require: A Level/IB Higher Level Mathematics and A Levels/IB Higher Levels in two other science subjects, see also subject requirements for Year 1 options
- Further guidance: In exceptional circumstances, applicants with only two science/mathematics subjects and Biological Sciences applicants without Mathematics may be considered.
See Entrance requirements and Choosing your post-16 subjects for additional guidance and conditions of entry.
A Levels
Your subject choices at A Level may restrict your Part IA subject choice. The more useful subject combinations are:
- A Level Chemistry, A Level Mathematics and A Level Physics
- A Level Physics, A Level Mathematics and A Level Further Mathematics
- A Level Biology, A Level Chemistry and A Level Mathematics
International Baccalaureate
The advice above about A Level subject combinations also applies to the IB.
- Higher Level subjects will satisfy A Level subject requirements
- For Natural Sciences (Physical), if taking Higher Level Mathematics, applicants are expected to take Analysis and Approaches. If this option is not available at your school, please contact the College that you wish to apply to directly for further advice and guidance.
- For Natural Sciences (Biological), if taking Higher Level Mathematics, we recommend Analysis and Approaches for the most competitive application, however Applications and Interpretations will also be considered.
Other examination systems
We expect applicants taking other recognised qualifications to have a level of understanding in science and mathematics roughly equivalent to those applying with A Levels.
Refer to our main Entrance requirements pages and consult a College Admissions Tutor for further advice.
Admission assessment
All applicants for Natural Sciences (including applicants to mature Colleges) are required to take the Natural Sciences Admissions Assessment (NSAA) at an authorised assessment centre (usually your school or college), for which you must be registered in advance.
Please see the Cambridge Admissions Testing website for information about dates and registration deadlines, and check admission assessments for further details.
Assessment format
The NSAA Section 2 Biology component is being updated for 2022. From November 2022, Section 2 Biology will assume knowledge of advanced topics, bringing it in line with Section 2 Physics and Chemistry, which already assume knowledge of advanced topics. See the updated specification document and specimen papers below for details.
Natural Sciences Admissions Assessment Specification 2022
- Section 1: Multiple choice questions in mathematics plus one science (Biology, Chemistry or Physics) (60 minutes)
- Section 2: Extended multiple choice questions in Biology, Chemistry or Physics (60 minutes)
Please note that your performance in the assessment will not be considered in isolation, but will be taken into account alongside the other elements of your application.
Specimen and past papers

Submitted work
Applicants are not typically asked to submit examples of written work. Some may be asked by their College to do some reading in advance of their interview, but if this is required the College will provide full details in the letter inviting the student to interview.
All undergraduate admissions decisions are the responsibility of the Cambridge Colleges. Please contact the relevant College admissions office if you have any queries.
Typical Natural Sciences entrants (A Level and IB)
Natural Sciences (Biological)
For 2017, 2018 and 2019 entry, the majority of entrants from an A Level background achieved at least grades A*A*A* (76% of entrants). These successful applicants typically took Mathematics (99%), Further Mathematics (37%), Biology (98%), Chemistry (96%) and Physics (26%). In addition to Mathematics A Levels, the percentage of entrants taking all three of Biology, Chemistry and Physics was 22%, two of the sciences 75% and only one of the sciences was 3%. For the same period, the majority of IB entrants achieved at least 43 points overall and/or grades 777 at Higher Level.
Natural Sciences (Physical)
For 2017, 2018 and 2019 entry, the majority of entrants from an A Level background achieved at least grades A*A*A* (91% of entrants). All of these successful applicants took Mathematics, 90% took Further Mathematics, 8% took Biology, 89% took Chemistry and 96% took Physics. In addition to Mathematics A Levels, the percentage of entrants taking all three of Biology, Chemistry and Physics was 6%, two of the sciences 81% and only one of the sciences 13%. For the same period, the majority of IB entrants achieved at least 43 points overall and/or grades 777 at Higher Level.
