The IB Computer Science course explores the fundamentals of computational thinking and problem-solving, preparing students to understand, design, and evaluate solutions to real-world challenges. Students learn to apply abstraction, algorithms, and system design across a wide range of contexts.
The course balances theoretical foundations (data, systems, networks, computational models) with practical skills (programming, databases, and project development). Students also complete an Internal Assessment (IA), developing a working computational solution for a real client, and (at Higher Level) study additional advanced topics such as resource management and abstract data structures.
The course equips students with both the technical knowledge and critical thinking skills needed for university studies in computer science, engineering, data science, and related fields.
Prerequisites
• Strong interest in problem-solving, technology, and logical thinking
• Prior exposure to mathematics at GCSE/IGCSE or equivalent level
• Basic programming experience (preferred but not mandatory)
• Solid English reading/writing skills for analysis and extended responses
Core Topics (SL & HL)
1. System Fundamentals
• Computer organization
• System design basics
• Problem-solving and system development life cycle
2. Computer Organization
• Hardware, machine representation of data
• Binary, Boolean logic, and low-level representation
3. Networks
• Local and global networks
• Protocols and security issues
• Internet fundamentals
4. Computational Thinking, Problem-Solving, and Programming
• Abstract thinking and algorithm design
• Programming constructs (variables, loops, conditionals, functions)
• Arrays, recursion, searching and sorting algorithms
• Object-oriented programming concepts (classes, methods, inheritance)
⸻
Additional Higher Level (HL) Topics
5. Abstract Data Structures
• Stacks, queues, linked lists, binary trees
• Recursion with abstract structures
6. Resource Management
• System resources (memory, storage, CPU cycles)
• Resource allocation and concurrency issues
7. Control
• Operating system principles

• Includes documentation, justification of techniques, and evidence of testing
⸻
Extended Essay (Optional, across IB Programme)
• A 4,000-word independent research paper
• Topics may include algorithm efficiency, AI ethics, cybersecurity issues, or computational models
