Master IB Computer Science, from computer fundamentals to object-oriented programming, with a plan built around your exams and your IA.
Free, no-obligation chat · Affordable plans that fit your budget · Start this week
About this course
IB Computer Science asks you to do two things well: explain how computing systems work, and solve problems with code and clear computational thinking. Many students find the mix of theory questions, trace-and-write programming questions and a pre-released case study hard to balance, and the Internal Assessment adds a large independent project.
The current guide, first taught in 2025 and first assessed in May 2027, is organised into two themes. Theme A, Concepts of computer science, covers computer fundamentals, networks, databases and machine learning. Theme B, Computational thinking and problem-solving, covers computational thinking, programming and object-oriented programming, plus abstract data types at HL. Paper 1 covers Theme A and a pre-released case study, Paper 2 covers Theme B in Java or Python, and the Internal Assessment is a computational solution of about 35 hours. The old option papers and HL Paper 3 have gone.
Learn with an affordable 1:1 mentor who explains each topic with short examples and exam-style practice. There are no free self-study lessons for this course yet, but our Java and Python lessons support your programming.

Learn by doing
Timed sets of pseudocode tracing, program-writing and class-design questions, followed by a walk-through of each answer with your mentor.
Design a normalised database for a scenario, draw its entity relationship diagram and practise SQL queries on it.
Build your own one-page summary of the pre-released case study, linking each idea to the syllabus themes.
A small program with several classes, built step by step to practise inheritance, polymorphism and testing before you start your IA.
