Should I apply for a degree in computer science or physics?

I am going to year 13 in September and have always been thinking of doing a degree in computer science, and chose physics, maths and computing so I could do so. However, physics has been my favourite subject at A-Level and over the last 2 weeks or so I’ve been really fascinated by quantum mechanics, and have been doing loads of reading on it. Since I’m applying to Oxford or Cambridge, I have to make my decision soon. I realise CS is probably better for employment and money, but I think I would like to work with quantum computers, which can be done with both CS and physics degrees. Should I do physics or computer science? (Ps. Quantum mechanics isn’t the only thing I like about physics, I like the majority of topics covered at uni and A-Level)

Do CS - Camb definitely would cover quantum computing as I attended a lecture on it during a summer school, which was lead by one of their professors. CS is a more employable degree than Physics, but if you really want to do Physics there's no harm in doing it.

Actually, did your school offer FM? If it did, then you probably will be auto-rejected by Oxbridge for both courses. You *might* be able to get into NatSci (can't remember if CS counts as a science), but you won't get into CS or pure Physics.

They offered FM but I didn’t take it because I didn’t realise how important it was for oxbridge. I emailed them about it and they said I’d be considered, though it’s unlikely. However, they said if I did well on the admissions test, that would go in my favour having not done further maths. All I can do is hope and try my best.

Fwiw - physics is FAR better for employability than CS. CS has one of the highest unemployment rates of any subject because the degree content is often too theory heavy without practical work experience.

If you prefer physics then I would definitely recommend you apply for physics.

Really? I’ve heard that there’s lots of demand for CS degrees. I’ve just looked at the government case study which reports a 11.7% unemployment, which is surprising. What kind of jobs would I be looking at with a physics degree at entry level?

It might be worth asking your college if you can get some help/tutoring covering some FM topics to prep for admissions tests

I’m pretty sure they have tutoring closer to the test. As I’m still unsure wether I want to do physics or CS, I’ve been preparing for both the maths and physics tests anyway. No harm in that imo as it will help my school work as-well.

Hiya @mattjh-,

It's great to hear that you're so passionate about physics and computer science. Choosing a degree can be really challenging, especially when you have to consider your long-term career goals and interests.

I was just wondering if you have considered looking at interdisciplinary options like natural sciences. I don't know about Oxbridge but I know that at Lancaster, a natural sciences degree would allow you to take both computing and physics modules, allowing you to explore your interests over both subjects. This could allow you some more time to develop interests and you could specialise later on. Also this allows you to develop skills over a broader range, which may be beneficial to future employment.

This would be my advice going forward based on what you've said and my own experiences.

Talk to Current Students and Lecturers: Reach out to students and professors in both departments to gain insights into the coursework, modules, and potential career paths. I found the best way to do this was at open days.
Explore Quantum Computing: Research the specific roles and skills required in the field of quantum computing. This can help you understand how both physics and computer science degrees can align with your goals.
Consider the Long-Term: Think about where you see yourself after university. What excites you about each field in the long run?
Stay Open-Minded: Remember that your interests and goals might evolve over time. Your chosen degree is a starting point and doesn't determine your whole life.

Whichever path you choose, your enthusiasm and dedication will help you throughout your academic life. Good luck with you decision!

Hi thanks for your reply. I really like the look of Lancaster (especially the physics course) and am having it as one of my 5 choices. A natural science degree looks great. However, I’m worried that it might not hold as much weight as a single science honours, and that companies might be more favourable for someone with a more specialised degree. Hopefully, I can decide, with confidence, the subject I want to do before the UCAS deadline.
