Edexcel IGCSE Computer Science Paper 1 (4CP0 01) - 9th May 2025

i have cs right after business (edexcel) and I think im allowed to bring in any notes to have a quick glance at during my 30 min break, does anyone have any recs on specific topics that I should bring notes w me?

I really liked this paper I thought it was not as difficult as I had imagined. For the quantum question I was going to write entanglement but then I just said "They work in temperatures colder than deep space with low resistance" which was said in the textbook so idk if i got that mark but I also said that they used qubits so Im sure I got that one. The 6 marker was confusing at first I didn't imagine we'd get that but I don't think it was too bad I mostly talked about sensors and then also that you could connect it to a smartphone app that could use AI to give you suggestions and that the wearable tech could store personal bests in a small database to track things for athletes. For the lowest and highest value for the sign and magnitude I got -127 and 127, did you all get that too?

Yes to everything! My friends also mentioned the qubits, so you're good to go 🙂 The 6 marker was nice since it didn't require a lot of key terms.

anyone finished ?

Ngl, the 6 marker was nice. My classmates said they liked the paper, so I guess it was easy - it just happened to be that I hadn't revised the topics that came up 🥲 I wrote "extrachange" instead of "entanglement" for the qubit question because I knew that the word started with e but I couldn't remember it

Oh and what was that ethics question I saw smth like it on another past paper and was gonna write about professionalism but then I said "Being transparent with what data is used for" and "asking for consent to use people's data". Also for the Trace table I wasn't sure what to do but I did it with the input of 7 I put 7 as the number, set the boolean to False, and then in the row where we have the testnumber I did all numbers from 1-7 and for the display in the last line I put a 7. For the input of 9 I put the number as 9, the boolean false, and then testNumber 1 and filled in 2 and 3, and on the same line I set the boolean to true and did no display. Idk if that made sense but did you get smth similar?
