Options for Computer Science: A-level Physics or Economics?

If you didn't like physics at GCSE, and aren't planning on doing a physics degree/engineering degree then don't take it at A-level. It doesn't really get more interesting imo, rather it becomes more tedious and nitpicky.

No CS degree requires physics, and they certainly don't expect you to take it like you've mentioned. It's more a case of most applicants taking it as it's a popular combination. The only relevant subjects for CS at uni is maths+further maths. Choosing between econ and physics here won't change anything, so pick the one you think you'll enjoy more.

I just saw the part where you said you haven't studied Economics before. Not sure how my mind skipped that but that changes my perspective a little. I think you should take out some spare time and watch one or two videos of people teaching the content. Also, try to find other resources that show what type of content you'll be learning. If it still seems like something you'll like, you can go for it.

I honestly wouldn't recommend making such a leap if you haven't done Economics before. I know some people can do it but it's more challenging to go from zero knowledge to A Level knowledge as opposed to the gap from GCSE knowledge to A Level knowledge. However, it can be done and has been done.

Hi, as someone who applied for maths and cs at very selective universities this year, I heavily researched into what unis are really looking for and I can confidently say none of them will advantage you for having physics (or even computer science), so that is a myth. Most Russell groups require a level maths, and if you're applying to any of Imperial, Cambridge and Oxford you should have a level further maths as well. The third subject can be anything, just make sure it's something you enjoy and can get a good grade in (applicants with four subjects aren't given any advantage over those who have three, by the way, but if you must take a fourth, make sure it's one you enjoy and are good at).

Thanks for your reply, I don't get the impression that economics GCSE is that common (my school didn't offer it anyway) so I know the sixth form teach assuming no prior knowledge. I definitely agree with your point though, I'm going to take a good look at some videos and textbooks before I make my decision.

You're welcome . I wish you the best on the uni admissions journey. You're on the right track. Don't forget to take breaks and rest when you need to!

That's interesting to hear - I think I had assumed it would be an advantage because so many applicants seem to take it (85% of successful candidates at Cambridge I read, however that would be a very aspirational university for me). I suppose it's a case where correlation isn't necessarily causation, people studying maths and CS just tend to also like physics. Thank you.

Yeah economics GCSE definitely isn't a common one and many people doing economics A-level won't have done it so don't let not having the GCSE stop you
