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.
What Will You Learn?
- 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.
Material Includes
- Multiple Interactive Exercises
- Practice Material
- Bonus Material
- Video Lectures
Requirements
- It is recommended that you note down all lectures in your notebook for better reference. You may practice programming exercises using tools such as Python IDLE or VB.NET.
