Essential subjects

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.

Desirable subjects

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.

ADMISSIONS ASSESSMENT

Applicants for Natural Sciences will need to sit the Engineering and Science Admissions Test (ESAT) in mid-October as part of the application to the University. You must register for pre-interview assessments so please do review this information carefully. Further information is available .

Why Choose St John's for Natural Sciences (Biological)?

Plate from a book showing a flower, a butterfly and a caterpillar

St John's College has an illustrious and inspiring history in Natural Sciences, with countless significant contributions at the frontier of these disciplines and eight Nobel Prizes in Natural Sciences awarded to members of St John’s, including the geneticist Frederick Sanger (with two Prizes) and molecular biologist Maurice Wilkins.

You’ll be equally inspired by the outstanding academics in St John’s today. They are internationally recognised for their cutting-edge research, from pioneering work on gene regulation through RNA to mapping the cognitative architecture of the brain, and from cereal symbiosis to foetal development. This means that your College teaching comes both from leaders in their field and from newly established researchers, full of innovative ideas.

We have a thriving student community in Natural Sciences – around 100 undergraduates and a similar number of postgraduates. This vibrant academic community means that, however you choose to specialise as you progress through the Tripos, it’s likely that several ��ճԹ� at St John's will have chosen the same track.

Our student-led Natural Sciences society, the Larmor Society, organises talks and social events – a great way to get to know ��ճԹ� in years ahead of you and benefit from their experience.

We award academic prizes each year to our highest achieving ��ճԹ� in Natural Sciences, recognising and rewarding their hard work and successes.

Supporting your studies

Academic skills support

All St John's ��ճԹ� have access to academic skills support throughout their studies. Academic skills workshops are offered throughout the academic year, and focus on a variety of topics including general study tips, essay-writing skills and revision strategies.

Some subjects hold compulsory academic skills workshops during the Michaelmas term. If you require individual support you can contact one of our Academic Skills Advisers, who each have a range of specialities, including essay writing tips, numeracy, presentation skills, prioritisation and revision skills. We have specialists in Arts and Humanities and in STEM, and in particular in Engineering.

Undergraduate Academic Research Project (UARP) Awards

St John's offers a number of grants to undergraduates who want to pursue academic research projects or Summer School courses related to their subjects at a University (including Cambridge) or other approved academic institution during the Long Vacation.

In addition to a general fund which covers all subjects, several subject-specific funds are also available. The Peter Munn Fund is dedicated to supporting Engineering projects. The Parsons Fund provides grants towards projects with links to Greece (Modern or Ancient) or the Eastern Mediterranean, as well as funding music-related projects. The Robert Tong Bursary offers free accommodation and access to the Library at Queen Mary, University of London during a set period.

All undergraduate ��ճԹ�, including finalists, are eligible to apply for these awards.

‍

Exchange Programmes

St John's is proud to collaborate with a number of great institutions to provide exciting cultural and academic exchanges.

Our current exchange partners include Caltech Scholars exchange, Collegio Ghislieri di Pavia University Exchange, Heidelberg University Exchange, Nagoya University Exchange Scheme and NUS Research Exchange Programme.

I’m from Hungary, and the Natural Sciences course at Cambridge is internationally recognised for its flexibility - we can focus on the areas that interest us most. I’ve also had the opportunity to complete an integrated Master’s, which isn’t always an option in other biochemistry courses.

The Larmor Society for Natural Sciences ��ճԹ� here at St John’s is very active, and there’s a great relationship between ��ճԹ� and Fellows, as we see them regularly - both formally and informally.

There are so many quirks I love about St John’s, like climbing the Chapel Tower to enjoy the views over Cambridge. There are lots of international ��ճԹ� at St John’s, and plenty of opportunities to socialise with others from Hungary and across Europe - it’s a great community.

St John’s does feel a bit like Harry Potter, I think this is the closest you can get to Hogwarts, especially with Formal Halls – it feels special every time I walk in

At school, I really liked all the sciences, including maths, and so I found it really hard to pick a subject to study at degree level, but I really like the interdisciplinary aspect of Natural Sciences. You can do, for example, Earth Sciences, which I didn't think I would do as one of my modules when I applied, but I wouldn't have had the opportunity to even try it if I hadn't picked this subject.

Being surrounded by academics has made me consider research more. Reading the Fellows’ papers is really cool because it exposes you to that world

My A-levels were biology, chemistry, maths and Mandarin but I couldn’t decide which science to do, and Natural Sciences at Cambridge sounded perfect. Being surrounded by academics has made me consider research more. Reading the Fellows’ papers is really cool because it exposes you to that world.

St John’s is a big college with lots of accommodation, it’s in the city centre, on the river, and very pretty. It’s weird how normal it feels now to cross the Bridge of Sighs every day, and the community feel here is what I was hoping for.

Applying

Successful applicants normally have outstandingly good GCSE results and you need a firm scientific foundation (likely to include Mathematics) for the subjects that you will take in the very broad first year of the Natural Sciences Tripos.

In your personal statement you should tell us how you’ve gone beyond your school curriculum in Sciences and Mathematics. For example, participation in subject Olympiads, the scientific books you've read and videos you've watched, perhaps online lectures or following research stories from institutions like the Wellcome Trust.

If you've had the chance to do some sort of scientific work experience you should also include this – but don’t worry if you haven’t had the chance to do this, it won't harm your application.

We expect to admit about 30 ��ճԹ� to read Natural Sciences every year, with approximately half classed as ‘Biological’ and half as ‘Physical’ Sciences. However, these classifications are very flexible, and ��ճԹ� often mix modules from the biological and physical sciences, or change their preferred area entirely. In our last round of applications, we made offers to roughly 25% of Biological applicants.

If you are invited to interview, you will have two interviews by the Director(s) of Studies and other teaching Fellows, each lasting 20-25 mins.

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.

One of the interviews will be concerned with subject-related topics, but we do not expect you to have detailed prior knowledge of topics outside the areas you have covered at school. The interview is not a test of memory, but is concerned with exploring your ability to think through scientific problems. Often the problem will involve interpretation of a graph or similar scientific figure.

The other interview will set mathematical problems that are asked in the context of Biology or Chemistry. We do not use a digital whiteboard, but you should have a pencil and paper to hand.

Poet Laureate

By Paul Hodgson 2006 © St John's College, Cambridge

Sanger arrived at St John's in 1936 to study Natural Sciences. His work on amino acid sequences and protein structures, particularly insulin, earned him a Nobel Prize in 1958, followed by a second in 1980 (jointly with Walter Gilbert) for his work in sequencing DNA. Regarded as the father of genomics, his research underpinned our understanding of genetics. He is one of only four people to have received two Nobel prizes, and the only person to have been awarded the prize twice for Chemistry. The Sanger Institute in Cambridge is named after him.
