Cambridge 0478 · Edexcel 4CP0
Live 1-on-1 online computer science tutoring for Cambridge, Edexcel and IB students worldwide. Students who struggle with Computer Science are usually not struggling with the subject — they are struggling with how it has been taught. Once the underlying logic is clear, everything from pseudocode to algorithms starts making sense.

Quick answer: Velocity Tuition Academy provides online 1-on-1 Computer Science tutoring for IGCSE, A-Level and IB students across Cambridge and Edexcel, covering Cambridge IGCSE Computer Science (0478), Edexcel IGCSE Computer Science (4CP0), Cambridge A-Level Computer Science (9618) and IB Computer Science at HL and SL. Tutors teach programming (Python and pseudocode), algorithms and theory by coding live, and every student starts with a free diagnostic.
Our Computer Science teachers are experienced Cambridge, Edexcel and IB specialists who teach the subject conceptually — not just as a collection of definitions to memorise. They make algorithms, data structures, and programming logic genuinely understandable.
Computer Science marks are lost to pseudocode that does not follow the expected format, algorithm designs that work logically but are written incorrectly, and theoretical questions requiring precise definitions. We identify exactly where marks are being lost.
Sessions follow a logical progression: understand the concept, trace through examples, write pseudocode or code correctly, then test under past paper conditions. Programming tasks are practiced live in sessions so feedback is immediate.
The boards split theory and programming differently. Cambridge IGCSE is two written papers; Edexcel adds a 3-hour practical on a computer; the Cambridge A Level ends with a practical paper.
Both papers are written; Paper 2 includes a scenario-based question. No calculators.
Paper 2 is taken on a computer in Python, C# or Java.
Each paper is 25% of the A Level; AS Level is Papers 1 and 2.

From IGCSE 0478 and Edexcel 4CP0 to A-Level 9618 and IB Computer Science, the tutor teaches that exact syllabus.
Most Computer Science mark losses at IGCSE and A-Level are not conceptual — they are presentational. Wrong pseudocode format, missing variable declarations, algorithm steps in the wrong order. These are fixable patterns.

My child's algorithm is logically correct. The program would work. But they wrote the pseudocode in a format the Cambridge mark scheme does not accept, and lost 6 marks on a question they completely understood.
We train Cambridge and IB pseudocode format explicitly. Every algorithm is written in the correct style, with correct indentation, variable naming, and logical structure. Over time, this becomes automatic.
The four stages of a Computer Science course with us.
A free Computer Science trial checking theory, logic and problem-solving, then a parent briefing.
Computer Science tutors specialise in Cambridge, Edexcel or IB and know how theory answers and pseudocode are marked.
Computer Science topics, from data representation to algorithms, are taught in order with coding tasks, theory questions and a monthly parent report.
Exam preparation means timed papers, tracing and writing pseudocode, and fixing the theory definitions students often lose marks on.
Programming skill grows with regular practice, so starting early makes a real difference.
Sitting Computer Science this session? Theory and algorithm skills can still improve if lessons begin now.
Discuss Timeline →Starting now for May/June 2027 leaves time for the full Computer Science syllabus, coding practice and past papers.
Start Planning →Starting well ahead lets students build coding confidence and revise theory topics more than once.
Plan Ahead →We tutor Computer Science students 1-on-1 across all our cities. In the Gulf, see our hubs for Dubai, Abu Dhabi, Riyadh, Jeddah, Doha, Kuwait City, Manama and Muscat. In Egypt: Cairo. In Southeast Asia: Singapore and Kuala Lumpur. In the UK: London and Manchester. Families in Dubai can also see our dedicated Computer Science page for Dubai.

This is the biggest structural split of any subject we teach, and it decides how a student should prepare from day one.
Cambridge 0478 is entirely written. Paper 1, Computer Systems, runs 1 hour 45 minutes for 75 marks on Topics 1–6. Paper 2, Algorithms, Programming and Logic, is also 1 hour 45 minutes for 75 marks on Topics 7–10, and ends with a 15-mark unseen scenario requiring an algorithm in pseudocode or program code — Cambridge expects roughly 30 minutes on that question alone. Calculators are not permitted in either paper. Programming is examined on paper.
Edexcel International GCSE Computer Science (4CP0) takes the opposite approach. Paper 1 is a 2-hour written exam worth 80 marks. Paper 2 is a 3-hour practical programming examination, also 80 marks, sat at a computer, with a choice of Python, C# or Java.
The consequence is real: a Cambridge student must be fluent writing pseudocode by hand under time pressure; an Edexcel student must be able to build, run and debug working code in a three-hour sitting. Practising the wrong one is the most common preparation error in this subject.
Computer Science depends heavily on Maths, and students heading for engineering often add Physics. Our guide to IGCSE subjects for engineering covers the combination universities expect.
