Natural Sciences is the odd one out in the UCAS catalogue. It’s almost a Cambridge-specific course, with a handful of other universities running their own versions. That makes the Natural Sciences personal statement an unusual document to write, because it has to satisfy more than one kind of admissions tutor at once. The questions below are the ones students actually ask us when they start drafting.
What is Natural Sciences actually for?
It’s a degree for students who want to study two or three sciences seriously at undergraduate level rather than picking one at 18. The course exists because some of the most useful scientific work sits between disciplines: biochemistry, biophysics, materials science, computational biology. If you already know you want to be a chemist and only a chemist, a single-subject Chemistry degree is the better fit. Nat Sci is for the student who genuinely can’t decide between, say, physics and chemistry, and who wants the first year to inform that choice.
How does the Cambridge Natural Sciences Tripos work?
The Cambridge Natural Sciences Tripos is the original. In Year 1 you pick three experimental sciences plus a maths option, so the breadth is real. Year 2 narrows you to two subjects. Year 3 specialises into one, and a Part III year specialises further. The course shape is a funnel: broad at the top, single-subject by the end. Your Natural Sciences personal statement needs to show you understand that shape and that you’ve thought about which sciences you’d want to keep when the funnel narrows.
Which other universities offer some version of Natural Sciences?
Durham, UCL, Bath, Lancaster, Leicester and Exeter all run Natural Sciences degrees, though each is structured differently. Durham lets you build your own combination across a wider menu. UCL’s Natural Sciences ties closely to the science faculty’s research streams. Bath and Lancaster offer more applied combinations. None of them are quite the same shape as the Cambridge Tripos, so if you’re applying to two or three Nat Sci courses plus single-subject options, you need a statement that doesn’t sound like it was written for one specific course.
Do I have to commit to a subject in my statement?
No. And in fact, sounding too committed to one subject can hurt you at Cambridge, where tutors want students who genuinely want breadth. But the opposite mistake is more common: students treat Nat Sci as a way to avoid choosing, and the statement reads as vague. What admissions tutors want is genuine interest in two or three specific sciences, with specific reasons. “I love science” is the death sentence. “I want to keep studying physics and chemistry because the questions I find most interesting, like how solar cells actually convert photons to current, need both” is the live version.
Which subject combinations make sense?
Physics and maths is the strongest pairing for students heading toward theoretical or computational work. Biology and chemistry is the classic pre-medical or biochemistry route. Chemistry and physics points toward materials. Biology and earth sciences points toward ecology, climate, and evolution. Pick the pairing that matches what you’ve actually been reading and doing, not the one you think sounds most impressive.
What reading should I reference?
Choose books that cross disciplines rather than sit inside one. The Selfish Gene by Richard Dawkins is a biology book that’s really about information theory. Anything by Stephen Hawking, especially A Brief History of Time, crosses physics and cosmology. The Hidden Life of Trees by Peter Wohlleben mixes botany, ecology and chemistry. Lab Girl by Hope Jahren is a memoir about being a working scientist that touches geology, botany and chemistry. The Emperor of All Maladies by Siddhartha Mukherjee crosses biology, chemistry and medicine. Reference one or two of these properly, with a specific idea you took from them, not a list of titles.
How is this different from a single-subject statement?
A Chemistry personal statement can be one long argument for chemistry. A Natural Sciences personal statement has to do two things at once: show real interest in each of your chosen sciences, and show that you find the links between them genuinely interesting. That’s a harder rhetorical job. You can’t just write two half-statements stapled together.
What if I’m also applying for single-subject courses?
This is the question that catches most applicants out. UCAS sends one statement to all five of your choices. If you’ve put Cambridge Nat Sci, Durham Nat Sci, and three single-subject Chemistry courses, that one statement has to satisfy a Cambridge Nat Sci tutor who wants breadth, and a Bristol Chemistry tutor who wants depth. The way through is to lead with a specific scientific question that genuinely needs more than one subject, then show real chemistry depth inside that question. The Chemistry tutor sees the chemistry. The Nat Sci tutor sees the cross-disciplinary instinct.
When does Natural Sciences tutoring help?
A Natural Sciences tutor is most useful at the structure stage, before you’ve written paragraphs you’re attached to. We help you pick which sciences to lead with, which book to anchor your reading on, and how to phrase your interests so the statement reads as one argument rather than a checklist. The Natural Sciences personal statement rewards students who sound like they’ve already started thinking like a scientist, not like they’re hedging.

Make your Natural Sciences statement connected
Harry Godfrey, co-founder of The Degree Gap, supports students applying to competitive UK universities with focused academic applications.
Watch this if your draft has lots of science in it, but no clear thread linking biology, chemistry, physics, maths, or real research problems.
Get University HelpOur personal statement process for Natural Sciences
We do not begin by forcing a polished draft out of you. We begin by finding the academic material that will make the statement worth reading: your genuine interests, your supercurricular evidence, and the ideas that can become a stronger argument.
Research and academic direction
We start with a consultation to understand your interests, extracurriculars, and supercurriculars. Then we help you branch out from that core interest into stronger academic evidence: books, lectures, articles, podcasts, YouTube explainers, projects, competitions, or other subject-specific research.
Opinion, reflection, and story
We then collate the best material and ask what you actually think. Do you agree with the author? Did the lecture change your view? What did you find surprising, limited, or unresolved? We do not want a Wikipedia entry. We want the statement to sound like a thoughtful student developing a real academic story.
Drafting, editing, and tutor support
You write the first draft, because the statement has to be yours. We then edit it closely: structure, phrasing, evidence, paragraph order, and whether the subject argument is strong enough. When you reach out, we will usually begin with a consultation call with Harry Godfrey, one of the founders, or another senior member of the team so we can build the right support package for you and match you with the right tutor.
Natural Sciences personal statement FAQ
How does the Cambridge Natural Sciences Tripos affect what I write?
The Tripos funnels you from three experimental sciences plus maths in Year 1 to a single subject by Year 3. Your draft has to show you've understood that shape and have a view on which two sciences you'd want to keep. Don't claim to love all five sciences equally, the Tripos forces a narrowing and Cambridge tutors want to see you've already started thinking about it.
How do I write one statement that works for Cambridge Nat Sci and single-subject backups?
Lead with intersections rather than declared favourites. Biophysics, biochemistry and materials science all sit between disciplines, and writing about a question that bridges chemistry and physics reads well at Cambridge while still proving chemical interest at Manchester or Imperial. Avoid the line I can't choose, which signals indecision to a single-subject tutor at Durham or Bristol.
What reading actually helps a Natural Sciences draft?
Two books with technical content, one per discipline, beat a list of pop-science titles. Richard Dawkins's The Selfish Gene is fine as one reference but it isn't enough on its own. Pair it with something like Peter Atkins's Galileo's Finger or a real undergraduate-level chapter from a textbook you've worked through. Cambridge wants signs you've engaged with content harder than A-Level, not a longer bibliography.
