Computer Science (SL/HL)

Learn how computers work, how software is created, and how technology shapes the modern world. The syllabus covers system fundamentals, computer organization, networks, computational thinking, algorithms, and programming, alongside the ethical and social implications of technology. Students develop the ability to analyze problems, design effective digital solutions, and apply computational logic in practical scenarios. Programming is taught alongside theoretical concepts, ensuring students can both understand and create technology.

Both Standard Level (SL) and Higher Level (HL) students study the same core content, but HL extends the depth and complexity to include more advanced data structures, additional algorithm design, and greater emphasis on computational logic and abstract thinking. HL students also tackle a more challenging case study and extended assessments, requiring sophisticated programming solutions, deeper systems analysis, and advanced evaluation skills.

Many students find IBDP Computer Science challenging due to the need to master both theory and practical coding skills simultaneously, the abstract nature of computational thinking and algorithm design, and the problem-solving required under time pressure in assessments. For HL, the greater volume and complexity of content — especially advanced algorithms and data structures — can be particularly demanding.
