Cambridge O Level Computer Science 2210 – Paper 2: Problem-solving and Programming

The University of Cambridge O Level Computer Science 2210 Paper 2 focuses on Problem-solving and Programming, assessing students’ ability to apply computational thinking, design algorithms, and develop programming solutions. The exam lasts 1 hour and 45 minutes and carries a total of 50 marks, evaluating students’ problem-solving skills and programming knowledge in various computing scenarios.

This compulsory paper includes practical problem-solving questions, which are derived from Section 2 of the syllabus content. The questions are designed to test students’ ability to design, interpret, and debug algorithms, as well as apply programming concepts using pseudocode and flowcharts.

A key objective of Paper 2 is to assess students’ proficiency in algorithm design, programming constructs, data handling, and debugging techniques. It also evaluates their ability to apply structured programming techniques and develop logical solutions to computational problems.

Key Aspects of Paper 2:

• The paper focuses on problem-solving skills, algorithmic thinking, and programming logic rather than theoretical knowledge.

• Students are expected to write and analyze pseudocode and flowcharts, demonstrating logical thinking and structured programming techniques.

• The exam assesses key programming concepts, such as loops, selection, variables, arrays, and file handling.

• Unlike Paper 1, which focuses on computing theory, Paper 2 evaluates students’ practical ability to solve computational problems and develop algorithms.

Topics Covered in Paper 2:
