Natural Sciences

Welcome to the King’s subject page for Natural Scientists. Here we provide a synopsis of the Natural Sciences course, details of how to apply and what we are looking for, and a few reasons why King’s is such a good place to study Natural Sciences at Cambridge.

Natural Sciences at King's

Why King’s? The Fellowship at King’s is strong in Natural Sciences, with several members of the Royal Society and even a sprinkling of Nobel Laureates. The large number of Fellows in the Sciences (more than twenty) combined with a thriving graduate community make King’s a vibrant place for undergraduates.

Many of the Fellows are actively involved in teaching both in the College and in the various departments. They also organise various other activities for ‘NatScis’ such as the Seminars for Biologists or the King's Maths-Physics Colloquium, both of which occur biweekly, and involve all levels of King’s scientists coming together for an intellectually stimulating and sociable evening.

There is also a King's Undergraduate Maths and Physics Society, which was set up by students to encourage undergraduate research. Each event has three fifteen-minute talks by current undergraduates. They present work to other students and academics, followed by discussion over drinks. The events are chaired by a member of the teaching staff, and the atmosphere is supportive and not too formal, with most of the audience being undergraduates who share interests and a similar level of knowledge. The society is also very helpful to students who want to do internships, putting them in contact with others who already have experience of how to find places and funding.

The Natural Sciences course

The Natural Sciences course (or Tripos as we call it here), is a broad-based and flexible course that allows students a tremendous degree of choice in the subjects they study. The aim is to produce scientists and not merely ‘physicists’, ‘biologists’ or ‘chemists’.

In the first year students study three subjects, choosing from Biology of Cells, Chemistry, Computer Science, Evolution and Behaviour, Earth Sciences, Materials and Mineral Sciences, Physics, and Physiology of Organisms; and students will also study Mathematics (one of two courses at different levels). In the second year there are twenty subjects to choose from, with students usually studying three, and in the third year there are seventeen possible subjects to study, with most students focusing on one.

Students who specialise in this way, even only in their third year, will get a superb education in their chosen subject at King's and in Cambridge, reaching a level as high, or higher, than at any equivalent University. For some subjects there is also the option of a fourth year, leading to an M.Sci. degree.

All experimental subjects have associated practical classes in the relevant departments, and there are supervisions (i.e. tutorials) for each subject every week in College for the first two years, and thereafter in the departments. Full details of the Tripos and its options are available on the Natural Sciences website.

Student Perspectives


Joanna, Mie, Jenny (left), Rebecca and Jonny have written about their experiences studying Natural Sciences, including what they have enjoyed, the transition from school and how to prepare, while (a different) Rebecca shares photos from a field trip. These accounts are well worth reading to get a sense of what it is really like to be a 'NatSci' at King's.

King's Science Fellows

Michael Bate is an Emeritus Professor of Developmental Neurobiology. He researches how the machinery underlying coordinated movement is genetically specified and assembled during embryonic development. This involves both analysis of how muscles are assembled, specified and patterned, and investigation of the way in which the neuronal circuits that control movement are generated and begin to function.

Andreas Bender

Andreas Bender (Director of Studies) is a Lecturer for Molecular Informatics with the Centre for Molecular Science Informatics. His work relates to virtual screening, the prediction of small molecule properties (such as solubility, logP, pKa) and the integration of biological and chemical data.

A photo of Anne Cook

Anne Cooke is a Professor of Immunobiology and runs a research laboratory studying the regulation of autoimmune disease, in particular Type 1 diabetes. Her work focuses on studying factors that influence the development of diabetes, how this disease might be prevented and also treated. Her laboratory also studies tissue repair processes and the ways in which stem cells might be used to replace damaged tissue.

George Efstathiou

George Efstathiou is a Professor of Astrophysics and Director of the Kavli Institute for Cosmology at Cambridge. He has contributed to studies of large-scale structure in the Universe, galaxy formation, dark energy and the cosmic microwave background radiation.

Stephen Fried

Stephen Fried is a Junior Research Fellow at King's and a visiting researcher at the MRC Laboratory of Molecular Biology. Though reared as a physical chemist, Stephen's current research efforts have drifted toward the fields of molecular biophysics and synthetic biology. To him, two key questions are: How do Nature's fantastic machines (proteins, nucleic acids) actually *work* at the physical, molecular level? And how can this knowledge be exploited to design biomolecules with enhanced (or unnatural) functions?

Chris Gilligan

Chris Gilligan is Professor of Mathematical Biology and head of the School of Biological Sciences. He works on disease, studying the invasion, persistence, scale and variability of epidemics within changing agricultural landscapes.

A photo of Julian Griffin

Applying to study Natural Sciences at King’s

applying for natural sciences

Applying with limited support?

We welcome candidates from all backgrounds, from all over the world. The application process for all subjects is explained on our how to apply page, which we advise applicants to read thoroughly in combination with the specific details below about the options, subject requirements, pre-interview-assessment, and interviews in Natural Sciences. We take fifteen to twenty students per year, broadly divided between those with ‘biological’ and ‘physical’ interests.

course options

All candidates apply for Natural Sciences on the UCAS form. On the SAQ (or the COPA, if you are an overseas student), you will be asked to choose between:

  • Natural Sciences (Biological)
  • Natural Sciences (Physical)

For details of these two options, please see the course overview.

Subject requirements

The University publishes information about subject combinations for the Natural Sciences course. Ideally, you will be studying at least two experimentally based science subjects, and be expected to meet our entrance requirements. If you will be applying for Biological Natural Sciences without Maths at A level, IB Higher or equivalent, there will be some maths work to do over the summer before you start the course.

pre-interview assessment

All candidates for Natural Sciences are required to take the pre-interview admissions assessment for Natural Sciences, which will take place in schools and other assessment centres on 2 November 2017. You must be registered in advance (separately to your UCAS application) to take the assessment. The registration deadline is 15 October 2017 and there is a deadline of 30 September if you normally get exam adjustments for a disability/Specific Learning Difficulty/long-term illness. Your assessment centre must register you for the pre-interview assessment (you can't register yourself).

Brief information about written assessments
Natural Sciences assessment format and specimen papers
Important: If you're not registered by 15 October (30 Sept for special arrangements) you won't be able to take the assessment. Unfortunately, this would mean that your application is not valid.

Your performance in the assessment will not be considered in isolation, but will be taken into account alongside the other elements of your application (see What are we looking for?).


Most (but not all) candidates are invited for interviews in Cambridge, which take place in early December. Candidates have two interviews, each with two members of the teaching staff in either Biological Natural Sciences or Physical Natural Sciences.

The interviews may include discussion of some of your own experimental work in science. If you are applying for Biological Natural Sciences, you will be asked to bring to the interview a note book detailing some recent experimental work you have undertaken, or an account of project work or of a field trip (this is not needed for Physical Natural Sciences).

You may also find the general general information about interviews helpful, and details of the interview options for international candidates are in the International Students section.

What are we looking for?

Shared academic interests help students to feel at home and thrive in their studies

The most important criteria are enthusiasm, dedication and potential and we consider each case on an individual basis. This course requires a considerable commitment in terms of time and energy, as it is one of the most up-to-date and challenging science undergraduate courses in the UK. But, as our many successful previous students will tell you, it is well worth the effort!

We will be interested in:

  • your existing examination results which we consider carefully, taking into account your personal and educational background;
  • your academic interests and motivation as explained in your UCAS personal statement and explored further in interviews;
  • your school reference and predicted grades for any exams you have yet to take;
  • your performance in the pre-interview written assessment for Natural Sciences;
  • how you approach scientific questions designed to make you think in interviews - our interviewers will work closely with you to assess your suitability for the challenges of Cambridge Natural Sciences.

At King's, we are looking for promise and potential. So although existing and predicted grades form a central criterion for admissions, we are careful to interpret grades in light of your personal and educational background. We assess each application individually. We are interested to learn about your existing knowledge and skills, but we endeavour also to find out how you would deal with the new materials and ideas you would encounter at Cambridge.
