About Cambridge IGCSE Computer Science (0478)

Cambridge Assessment International Education (CAIE) sets the 0478 Computer Science specification. Tutopiya's resources are organised against this exact specification, so the notes, past papers and practice questions all reflect the papers, tiers and mark schemes your child will actually sit.

Paper structure

Cambridge IGCSE 0478 has Paper 1 (Computer Systems theory, 1h 45min, 75 marks) + Paper 2 (Algorithms, Programming and Logic, 1h 45min, 75 marks). Edexcel 4CP0 has Paper 1 (Principles of CS) + Paper 2 (Application of CS Principles, on-screen). A Level Cambridge 9618 has Paper 1 + Paper 2 (theory) and Paper 3 + Paper 4 (algorithms / programming). IB DP CS uses Paper 1 + Paper 2 + IA (programming-based solution).

Grade boundaries

Cambridge IGCSE 0478 A* typically requires ~78–82% across both papers. Edexcel 4CP0 grade 9 ~80%. Cambridge A Level 9618 A* requires ~80% overall + ~90% on A2 papers. Boundaries vary per series.

How to revise Computer Science (0478)

Reading the textbook cover to cover isn't revision; it's reading. Here's how top CS students actually use these resources.

  • Start each topic with the Computer Science notes; read for understanding, not coverage
  • Drill topic-specific practice questions until you can explain your method out loud
  • Take an AI quiz after each topic to catch the weak spots you didn't know you had
  • Read the worked solutions even when you get a question right, to pick up faster methods
  • Attempt full 0478 past papers under timed conditions in the final 4 weeks
