Understanding Pearson Edexcel iGCSE CS (4CP0)

The International GCSE (iGCSE) focuses on core mathematical reasoning and programming principles that transcend borders. It consists of two major pillars:

📝

Paper 1: Principles of Computer Science

Written theory examination focusing on architectural principles, security protocols, networks, and representing values globally.

  • Binary, Hexadecimal, Unicode representation
  • CPU architecture & von Neumann components
  • Network structures, TCP/IP, and internet security
  • Environmental, ethical, and legal impacts
💻

Paper 2: Application of Computational Thinking

Practical programming examination. Students write, parse, and debug functional programs in Python, focusing on rigorous problem-solving.

  • Pseudocode structure & flowchart trace tables
  • Algorithm design, sorting, and searching logic
  • Array manipulations and file I/O handling
  • Data validation and comprehensive test plans
