The 'Physical' and 'Biological' classifications in Natural Sciences are very flexible, and students often mix modules from the biological and physical sciences, or change their preferred area entirely.

St John's College has a strong history in the Natural Sciences, including among our alumni the double Nobel Prize winning geneticist Frederick Sanger and the physicist Paul Dirac, one of the founders of Quantum Mechanics. We continue these traditions today, with a strong teaching fellowship maintaining broad interests across the sciences. There are at least fifteen Fellows and other teaching staff who are directly involved in supervising Natural Scientists in the College (see 'People'). Recent research by our teaching Fellows has been published in the world leading journals Nature and Science.

The Natural Sciences course at Cambridge is perhaps unique in the UK in its flexibility and broad scope. Throughout, the emphasis is on developing an understanding of principles so that graduates are well equipped to both understand and contribute to future scientific advances. The broad nature of the course is particularly well suited to modern science, where traditional subject boundaries are being abandoned in favour of cross-disciplinary approaches.

The supervision system is integral to teaching at Cambridge, and at St John's you will have regular supervisions, usually in groups of 2-3 students. In the first year you will have 4 supervisions per week, mostly with teaching fellows from the College. The College also offers considerable additional support, including an excellent library, grants towards the costs of essential books and laptop computers and prizes for academic excellence in Natural Sciences.

Many students spend the summer carrying out research projects in UK or European universities. Students can also participate in an exchange programme with California Institute of Technology.

Courses in Natural Sciences

The first year will involve choosing three (out of a possible eight) basic experimental subjects, plus an appropriate course in Mathematics. This will give you a thorough and broad foundation on which to build your chosen speciality. 

Second year students choose three subjects, giving them the opportunity to become more specialised in a particular subject, or to retain a broad approach. By the third year you will be specialising in one of sixteen subjects, chosen from a list that runs from Astrophysics to Zoology and includes Biochemistry, Chemistry, Materials Science, Plant Sciences, Psychology and Physics.

In all Natural Sciences subjects it is possible to graduate with the BA Degree after three years. Four-year courses leading to the degrees of BA and MSci are available in eight subjects including Biochemistry, Chemistry, Geological Sciences, Materials Science, Physics and Systems Biology, subject to appropriate examination performance.

Students who read Natural Sciences during their first one or two years may also complete their degrees in another subject: for example, Chemical Engineering, Mathematics, Electrical and Information Sciences, Management Studies or Law.

Entry Requirements

Natural Sciences (Physical): 3 Science subjects (which will include at least one mathematical subject). Most successful candidates offer both Mathematics and Further Mathematics at A2, or at least Further Mathematics at AS level. Further Mathematics is not a requirement, but opting to study it usually indicates a degree of comfort with mathematics which is of great benefit when studying physical science subjects. If you are taking Mathematics and Further Mathematics at A2 together with two additional subjects it is possible that we would ask you to obtain A*A*AA.

We take a flexible approach in the subject combinations we accept but, whatever the combination, it must be one that gives a sufficiently firm scientific foundation for the subjects that you would wish to take in the very broad first-year course. If you are in any doubt about the suitability of your combination of subjects as a preparation for the Natural Sciences Tripos please contact us well before the deadline for submission of a formal application for advice.

You will also be required to sit a pre-interview written assessment and a written test at interview stage (see below).


We expect to admit about 30 students to read Natural Sciences every year, with approximately half classed as ‘Biological’ and half as ‘Physical’ Sciences. However, these classifications are very flexible, and students often mix modules from the biological and physical sciences, or change their preferred area entirely. Whilst we view each application independently, students invited for interview will normally have an average above 85% in three relevant subjects plus at least 90% in one AS science subject (including Mathematics).

Those invited for interview will have three interviews. First a tutorial interview followed by two subject interviews by the Director of Studies and other teaching fellows. We conduct our interviews in a friendly and informal manner, and you should not feel too daunted by the prospect of them. No special preparation for the interview is necessary, or indeed desirable. The interview with the Natural Science Fellows will be concerned with subject-related topics, but we do not expect you to have detailed prior knowledge of topics outside of the areas you have covered at school. The interview is not a test of memory, but is concerned with exploring your analytical ability to think through scientific problems. Further details of the process are sent to students selected for interview.

Admissions Assessments

For Natural Sciences you will be required to take a pre-interview written assessment. For Natural Sciences Physical you will also be required to take a 1-hour written test set by the College, either before or after your interview. The test is designed to test ability in Mathematics and to see how candidates apply their mathematical ability to Physics and Chemistry. Students not taking Chemistry or Physics at AS level will not be penalized by their inability to answer questions on these subjects. The test is based on the core A-level syllabuses and is designed to be accessible to all applicants.

For the written test at interview some sample questions from previous years are available.

Decisions

We take account of all of the available information about you to assess your potential and thereby to make a decision about your application. This includes reviewing your academic record, reference, personal statement, interview performances, written test, pre-interview written assessment result, and anything else that is relevant. Should you narrowly miss an offer of a place, we are very active in placing your application in the Winter Pool and in informing other Colleges who are looking in the Pool.
