IGCSE Computer Science Notes
🚧 Under construction. 🚧
Below are my notes for Cambridge’s IGCSE Computer Science 0478 (for assessment from 2023 onwards, with last assessment in 2028).

To be added.
Question banks
I strongly believe that scoring 60+ out of 75 is very easy on the Paper 1, as it is mostly just rote memorisation. There is very little variation in the possible questions that can come up on Paper 1. As long as you have ‘memorised’ (although I would prefer using the word ‘understood’, as understanding is the best way to memorise) all the mark schemes in the question banks attached below, it is more than sufficient to score at an A* level.
I strongly recommend using Anki to memorise all the content.
This section will continue to expand, hopefully with all units added before the Summer 2027 exams.
Some more advice:
- I don’t think using these question banks is not the best substitute for learning the content. Use the textbooks, and other resources to properly immerse yourself in the course content first.
- There are often more marking points than marks available in a question. I suggest memorising more marking points than marks available to be safe. Also, not all the marking points make an equal amount of sense. Memorise what makes sense to you.
- Some questions appear once every 5 years, some appear every other examination cycle. Perhaps you may encounter one question per exam that has never appeared before. Towards the end of the course, I suggest opening up several past papers to spot which topics are most common. Some examples of common topics: Converting between different units, describing lossless/lossy compression, describing packet switching… Some examples of uncommon topics: Digital currency, some types of cyber security threats…
