// ABOUT THE COURSE
Built around the syllabus, not the textbook.
The IB Diploma Programme Computer Science course sits in Group 4 and develops computational thinking, problem-solving and an understanding of how systems work. It rewards students who can explain their reasoning — not just reproduce code.
Whether you take it at Standard Level or Higher Level, the course spans computer architecture, networks, data representation and algorithm design, culminating in an internal assessment where you build a real computational solution for a real client.

Gloria Solomon
IB DP COMPUTER SCIENCE TUTOR · SITE MANAGER
Hi, I'm Gloria Solomon — I run this site and teach every class personally. I work 1:1 with IB DP Computer Science students at both SL and HL, from first principles through to Paper 3 and the internal assessment.
Lessons are built around what you actually need next: the topic you're stuck on, the paper you're preparing for, or the IA you need to get moving. Message me directly and we'll start with a free 30-minute class.
