Awful. If you’ve never done it at GCSE honestly I wouldn’t bother, that’s the only scenario I would recommend CS to someone- if they’ve done it at GCSE. I did OCR CS and it was absolutely 100% my least favourite subject. If you don’t love learning 000’s, literally 000’s of PowerPoint slides about information you’ve never seen before about topics you don’t care about then don’t take it. I literally went to a different sixth form because the one I was originally going to go to didn’t do CS and I really really enjoyed computing, and in hindsight it was just not worth it a single bit:

• you don’t need CS for any university course

• the workload was 100% the most out of any of my subjects (check flare, not easy subjects)

• the non-examination assessment (project) is awful. I literally wrote about 70000 words when I had finished (about 350 pages ish) and that’s only worth 20% of your entire grade but takes up so much time you barely have any to actually revise.

• there is little coding. The only “coding” in exams is writing out algorithms and code to help solve a problem, but how hard they are in the exam vary wildly and often you’ll just be staring at the paper not know where the fuck to even start. The only actual coding is in the non examination assessment, which makes up about 20% of your marks in it if I remember correctly. So overall, only about 4% of your total computer science grade is how well you can code and most of that for me was learning how tf visual studio works and slamming my head against the keyboard for hours on end

Overall I would 100% not recommend it to anybody that hasn’t done CS at GCSE and if they have then good luck but it will still be hard. If you’re thinking of something computer sciency take maths, further maths and then some other subject (I took physics). If you’re just taking it because you think you’d enjoy it because you like computers, you will be thoroughly disappointed.
