Natural Sciences


The structure of the Natural Sciences Tripos is unique among science courses in British universities. It provides a very broad training in the first year (Part IA), in which you have to take three experimental subjects and one of the Maths options. A course from the Computer Science Tripos may be substituted for one of the experimental subjects. The second year (Part IB) allows some degree of specialisation, but the third (Part II) and possibly fourth (Part III) years are usually devoted to a single area of science, sometimes one that the student had not even met before coming to Cambridge. With seven sciences available in Part IA, and nineteen (plus Mathematics) in Part IB, the range of possibilities is huge.

Trinity has a very strong tradition in Natural Sciences. From Isaac Newton onwards, many famous scientists have studied or taught here, among them 29 winners of Nobel Prizes in Physics, Chemistry, or Medicine. The traditions of the past are reflected today in the size of Trinity’s teaching staff and its breadth of scientific interests. Those currently teaching Natural Sciences in the College are listed below, together with the subjects for which they are responsible.

If you apply for Natural Sciences at Cambridge you are asked to classify yourself as “biological” or “physical”. So far as Trinity is concerned the distinction is merely an organisational one and does not commit you to any specific course of study within the Natural Sciences Tripos. All applications are assessed in the same way and offers are made to those whom we think most likely to do well here irrespective of the subjects in which they hope to specialise.

Applicants are asked in advance of their interview which of their school subjects for the present interests them most but this is done only to guide us in matching interviewers to candidates. Everyone who comes for interview will be seen for about 45 minutes by two members of the teaching staff in Natural Sciences. Prior to this there will be a written component which will be used as a basis for discussion at interview. Candidates should familiarise themselves with the rubric and style of questions by attempting typical questions available below:

Although the interview is likely to focus on your declared particular interests you must be prepared to talk about any of your A-level subjects. As in other subjects at Trinity, the interview is strongly academic in character.

The standard conditional offer for Natural Sciences will be A*A*A; we may also ask for a high grade in a relevant subject being taken only at AS-level; comparable conditions are set for those taking the IB and other school-leaving examinations. We expect to admit roughly 30 people for Natural Sciences each year.

Applicants should be taking three sciences at A level including Mathematics. To study Physics at Trinity you will need either A-level Physics, or Mechanics modules in Further Mathematics.  If in doubt about the suitability of your choice of A-level subjects you should seek advice from the Admissions Office before submitting an application.

Admissions Assessment

All applicants are required to take the pre-interview written assessment for Natural Sciences at an authorised centre local to them (for a lot of applicants, this will be their school/college).

Assessment format

  • Maths/Science MCQs (80 minutes)
  • In-depth Science questions (40 minutes)

You must be registered in advance (separately to your UCAS application) to take the assessment – the registration deadline is 15 October 2016. Your assessment centre must register you for the pre-interview assessment; you’re not able to register yourself. See the written assessments page for information about assessment centres and registration.

The pre-interview written assessment for Natural Sciences will be taken on 2 November 2016.

Please note that your performance in the pre-interview assessment will not be considered in isolation, but will be taken into account alongside the other elements of your application.
