Program Overview
Cambridge IGCSE Computer Science is two subjects wearing one name. Half of it is how computers actually work, from binary and data transmission to hardware, networks and emerging technologies. The other half is thinking like a programmer: designing algorithms, writing and correcting real code, querying a database, and reasoning through logic circuits. Students who treat it as a memory subject stall on the second half, because you cannot memorise your way through writing a program you have never seen.
This course teaches both halves properly. It follows the current 0478 syllabus (version 5, for examination in 2026, 2027 and 2028) topic by topic, and it is built around the fact that the qualification is assessed by two written papers of equal weight, with no coursework. Paper 1 covers computer systems. Paper 2 covers algorithms, programming and logic. Neither can be neglected, because each is worth exactly half the grade.
The six-month structure moves in the syllabus's own order. Months 1 and 2 build computer systems from the ground up: data representation, data transmission and hardware. Months 3 and 4 finish the theory with software, the internet and its uses, and automated and emerging technologies, then add Boolean logic. Months 5 and 6 turn to the programming half: algorithm design, pseudocode, real Python, file handling, databases and SQL, and then full timed exam practice on both papers. Every class is live and small, and every programming concept is practised by actually writing code, because that is the only part of this subject that cannot be faked.
What Makes This Program Different
- Both papers taught in full and to equal depth, because each is worth exactly 50 percent of the grade and most students quietly neglect one of them
- Taught to the current syllabus (0478 version 5, for examination in 2026, 2027 and 2028), so nothing covered is out of date
- Real programming, not just pseudocode on paper: students write and run genuine Python, which is what makes Paper 2 straightforward instead of frightening
- The scenario question is prepared for directly: candidates may answer in pseudocode or in Python, Visual Basic or Java, and we drill the choice your child is strongest in
- Exam technique built in from the start: trace tables, dry runs, test data, and the difference between the marks for stating, applying and evaluating
- Live, small batches where your child writes code during class and gets it reviewed on the spot, not recorded lectures watched alone
