Natural Sciences

Students in a Chemistry supervision looking at a molecular model

Natural Sciences offers a wide range of physical and biological science subjects from multiple departments in a unique and demanding course. A broad first year is combined with increasing specialisation in the second year and the possibility of total specialisation in the third year.

The breadth of the course reflects the blurring of boundaries between the different sciences and before committing yourself to one department you study a variety of subjects, some of which may be new to you. This means you can change your mind about which subject to specialise in.

A-Level: A*A*A

IB Diploma: 42 points, with 776 at Higher Level

Please also read our Entry Requirements page.

Subject requirements

You will need A levels/IB Higher Levels (or the equivalent) in:

  • Mathematics
  • 2 other science or mathematics subjects

Please note, ‘science/mathematics subjects’ refers to Biology, Chemistry, Physics and Further Mathematics.

If you are taking the IB Diploma, we will require HL Mathematics Analysis and Approaches if you wish to apply for Natural Sciences Physical. For Natural Sciences Biological, we recommend Analysis and Approaches but we will also consider Applications and Interpretations.

For Natural Sciences Physical we will normally ask for an A* in Further Maths (or an A* in Maths if Further Maths is not being taken) and an A* in Physics or Chemistry.

For Natural Sciences Biological we may ask for an A* in specific subjects.

Why Trinity Hall?

Natural Sciences at Trinity Hall is a large and dynamic community, bringing together students and Fellows working across a wide range of disciplines.

You’ll be part of an active scientific environment with regular talks and events organised by student societies.

The College also has a strong record of scientific achievement among its alumni, reflecting its ongoing commitment to research and discovery.

The Trinity Hall NatSci Society run quiz nights or welfare drop-ins, and we have a Natural Sciences formal where everyone taking the subject and some Fellows all have a meal together, and that's really nice.

Admissions process

Written work

None required.

Admissions assessment

All applicants for Natural Sciences are required to take the Engineering and Science Admissions Test (ESAT) at an authorised assessment centre. You must register in advance for this test.

Please see the University’s admissions test page for more information.

Interviews

Two interviews of around 25 minutes each.

When applying for Natural Sciences at Cambridge, you will be asked to indicate whether you wish to apply for Biological or Physical Sciences. This will determine what kind of questions you will be asked at interview. At Trinity Hall, Biological applicants will tend to be asked questions about Biology and Chemistry, while Physical applicants will tend to be asked questions about Maths, Physics and Chemistry.

Each interview will be tailored to the individual and the subjects they have studied at school. However, interviews will cover some new ground as well – we want to see how well you deal with new material and with the application of your background knowledge to new problems.
