Computer Science 2210 : Olevel : Full Course

What does the examiner want from you in 2210 Paper 2 (O Level Computer Science)?

 

In Paper 2, the examiner wants to see how well you can apply your understanding of computer science concepts to practical situations. This paper focuses on problem-solving, programming, and logic rather than just theory.

Specifically, the examiner wants you to:

  1. Understand and apply logic – Use correct algorithms, flowcharts, and pseudocode to solve problems.

  2. Write correct and structured pseudocode – Follow the Cambridge pseudocode standard (using proper indentation, IF…THEN…ELSE, FOR/NEXT, WHILE, etc.).

  3. Use correct programming concepts – Show understanding of variables, data types, arrays, subroutines, and file handling.

  4. Trace algorithms accurately – Be able to dry-run code and show the correct output step by step.

  5. Interpret problem statements carefully – Understand what is being asked before writing pseudocode or flowcharts.

  6. Use clear and logical structure – Write answers that are easy to follow, showing good logic and understanding of control structures.

  7. Demonstrate practical understanding – Apply your knowledge to real-world computing scenarios, not just recall theory.
