Where Tutix is today
A ready-made IGCSE Computer Science program is planned and not available yet. You can start a IGCSE Computer Science class now: the tutor teaches live from your syllabus or notes. Ready-made programs exist for other courses.
The qualification
Cambridge IGCSE Computer Science is syllabus 0478. The 2026-2028 syllabus covers the 2027 and 2028 exams. A revised syllabus starts from 2029, so it is not the one you will sit in 2027 or 2028. There are no Core and Extended tiers, so every candidate is entered for grades A* to G. Exams are in the June and November series, and in March for centres in India.
The papers
| Paper | Title | Time | Marks | Weighting |
|---|---|---|---|---|
| 1 | Computer Systems | 1 h 45 | 75 | 50% |
| 2 | Algorithms, Programming and Logic | 1 h 45 | 75 | 50% |
Calculators are not permitted. Paper 2 ends with a 15-mark scenario question answered in pseudocode or in a programming language (Python, Visual Basic or Java).
What the marks test
Cambridge weights the marks of IGCSE Computer Science between three assessment objectives: knowledge and understanding of computer science (40%), applying that knowledge to a context, including analysing and designing problems (40%) and providing solutions by evaluating systems and making reasoned judgements (20%). Cambridge calls these weightings approximate.
| Assessment objective | IGCSE |
|---|---|
| AO1 Knowledge and understanding of computer science | 40% |
| AO2 Applying that knowledge to a context, including analysing and designing problems | 40% |
| AO3 Providing solutions by evaluating systems and making reasoned judgements | 20% |
| Assessment objective | Paper 1 | Paper 2 |
|---|---|---|
| AO1 Knowledge and understanding of computer science | 60% | 20% |
| AO2 Applying that knowledge to a context, including analysing and designing problems | 20% | 60% |
| AO3 Providing solutions by evaluating systems and making reasoned judgements | 20% | 20% |

Example
IGCSE Computer Science · Data representation · Binary
Convert the denary number 25 to binary.
Check by converting back: 11100 is 16 + 8 + 4 = 28. Which place values add up to 25?
A sample written to show how a class sounds. The scores show how the exam would credit each answer. Not a real learner.
What a ready-made program adds, and what it costs
Ready-made programs, such as IGCSE Physics, come with lessons and questions reviewed in advance, at five levels. The Free plan includes 45 live class minutes a month with no card; see the plans.
The twelve ready-made programs are drawn to scale, with a real lesson to read, on the Programs page.
Questions people ask
Does Tutix have an IGCSE Computer Science program?
Not ready-made yet; it is planned. Today you can start an IGCSE Computer Science class: type the subject, attach your own notes, and the tutor builds the classes around them.
What topics are in IGCSE Computer Science?
Data representation, Data transmission, Hardware, Software, The internet and its uses, Automated and emerging technologies, Algorithm design and problem-solving, Programming, Databases and Boolean logic.
What papers are in IGCSE Computer Science?
Paper 1, Computer Systems, 1 h 45, 75 marks; Paper 2, Algorithms, Programming and Logic, 1 h 45, 75 marks.
Are there Core and Extended tiers in IGCSE Computer Science?
No. There are no tiers, so every candidate is eligible for grades A* to G.
Which IGCSE Computer Science syllabus should I follow?
The 2026-2028 syllabus covers the 2027 and 2028 exams. A revised syllabus starts from 2029, so it is not the one you will sit in 2027 or 2028. Check the syllabus your school or exam centre is entering you for.
