A-Level Maths, Computer Science and...?

My son wants to do the same (maths and computer science - but not further maths) with the likelihood of then doing some sort of computer science related degree.

He has been weighing up doing either physics (which he felt was a better match but isn’t his favourite) or English language. I was somewhat surprised when his physics teacher said without doubt to do English. Turns out he is a degree course assessor and his advice is that maths and English a level will be accepted for pretty much any degree course, whereas physics would really narrow it down. Plus he said engineers, coders, mathematicians etc generally can’t write for toffee (his words not mine!) so it would be an excellent skill set to have.

I was going to say physics. If she likes history she could do that? I don't think it will make a great deal of difference so I think she should just do which one she thinks she will enjoy the most.
Business (according to my son) is quite an easy A Level.

What doesn't she enjoy about Business Studies? Economics is a bit more abstract (and gets more mathematical at university level), and might be more to her liking. Do any local sixth forms do tasters of subjects they might not have done at GCSE? Can she borrow a textbook to have a look at?

Before rejecting further maths, she might want to just look at which universities prefer their computer scientists to have it. (Even if they will accept applicants who don't have it, it may be hard work if others have it and she doesn't. Also, I think sometimes they are less sympathetic to those who have chosen not to do it, rather than just their school not offering it.) However if she's checked that out, then fair enough if she doesn't want to do it.

Mine was in a similar quandary. He had intended to do Maths,CS and Business but was not particularly excited about Business. He chose it more because his other strength was sciences, but he really did not want to do a science A-level.

Ds got a good grade in his DT GCSE, and decided to do 3d Design instead of Business. He is loving it, and finds that the 3 subjects complement each other very well. Also, no massive essays.

Look at Informed Choices website , to see impact of choices on university courses. And the A Level matching tool on Sacu Student - can play around with the third A Level and see what impact it might have (or not) on course choices.

Economics is interesting at that level. Need analytical skills to enjoy it so I'd say it goes well with her choices.

I would have said Physics to keep doors open.Obviously it’s a science though! Geography would be good too. What else does she enjoy in her GCSE subjects? What do computer science related degrees ask for? A third subject can probably be whatever she wants if maths and CS are 100% relevant.

She should do something she enjoys, A-level is a big step up from GCSE and I think they need to be interested in the subject to do well and keep motivated. Obviously if they need a particular subject for a certain degree/career path then they need to suck it up!
i also think you need to look at the subjects and try and get a balance between maths and written subjects plus look at how much coursework there is versus exams. DD dismissed one option as it would mean 4 very coursework heavy subjects and DS1 went for Georgraphy as his 4th as also doing physics, maths and further maths so Georgraphy which is loves was a good complement to the maths heavy subjects.
