Computer Science 2210 : Olevel : Full Course

Cambridge O-Level Computer Science 2210

The syllabus is divided into two papers:

Paper 1 – Theory (Typically 2 hours)

Paper 1 tests the student’s understanding of fundamental concepts of computer science. It includes multiple-choice, structured, and short-answer questions.

1. Data Representation

2. Communication and Internet Technologies

3. Hardware and Software

4. Security

5. Algorithms and Programming

6. Databases

7. Problem Solving

Paper 2 – Practical (Typically 2 hours)

Paper 2 tests the ability to apply practical skills in programming and problem-solving. Students are given tasks to implement, usually in a high-level language like Python, Java, or pseudocode.

1. Programming

2. Algorithm Implementation

3. Problem Solving in Practice

4. Data Representation and Manipulation

Key Notes

Paper 1 focuses on knowledge, understanding, and explanation.
Paper 2 focuses on practical skills and application of programming.
Both papers complement each other; theory knowledge supports practical work.

This full O-Level Computer Science 2210 course provides complete coverage of both Paper 1 (theory) and Paper 2 (practical). You will learn core topics including data representation, computer architecture, logic gates, and networking. The course also covers problem-solving, algorithms, and programming in Python, focusing on structured programming, file handling, and testing. Practical skills are developed through hands-on coding exercises and exam-style questions. By the end, you will gain a solid understanding of theory and practical programming, fully preparing you for success in the 2210 examination.
