Lesson flow
From confusion to calm, one lesson at a time.
Our tutors cover the theory and the practical programming skills — the combination most school lessons do not have enough time to develop fully.
Step 1
Pinpoint the gaps
We start with recent marks, confidence blockers, and the exact exam board so sessions feel personal from lesson one.
Step 2
Teach the mark scheme
Tutors connect concepts to examiner language, worked examples, and the habits that turn knowledge into marks.
Step 3
Track the lift
Parents see what changed after each session: topics covered, next steps, and the grade trajectory we are building toward.
What we cover
A syllabus map students can actually follow.
1Data Representation+
Binary, denary, and hexadecimal number systems, conversions between bases, binary arithmetic, two's complement, ASCII and Unicode, and image and sound representation.
2Communication & Networking+
Types of network (LAN, WAN), topologies, protocols (TCP/IP, HTTP, FTP), the internet, the World Wide Web, encryption, and cybersecurity threats.
3Hardware & Software+
CPU architecture (fetch-decode-execute cycle), memory (RAM, ROM, cache), secondary storage, input/output devices, operating systems, and types of software.
4Security, Privacy & Ethics+
Cybersecurity threats (phishing, malware, hacking), data protection, privacy issues, ethical impacts of computing, and the role of legislation.
5Algorithm Design+
Decomposition, abstraction, trace tables, flowcharts, pseudocode, searching algorithms (linear and binary), and sorting algorithms (bubble, insertion, merge).
6Programming Fundamentals+
Variables, data types, selection (IF-THEN-ELSE), iteration (FOR, WHILE, REPEAT-UNTIL), procedures and functions, arrays, and file handling — all in pseudocode and Python.
7Databases & SQL+
Database concepts, SQL queries (SELECT, WHERE, ORDER BY), creating and updating tables, and relational database design.

Common blockers
Where students struggle, and how we fix it.
1Writing pseudocode correctly+
CIE pseudocode has specific syntax requirements. We teach the correct keywords, indentation style, and structure for every construct — so students never lose marks for using Python syntax in a pseudocode answer.
2Tracing algorithms with trace tables+
Trace table questions are a consistent source of dropped marks. We practise systematically: set up the table headers correctly, step through each line, and track variable values precisely.
3Data representation conversions+
Binary, hex, and denary conversions under time pressure cause avoidable errors. We drill the column method for conversions until it is fast and accurate, then extend to two's complement and data size calculations.

Academic Excellence
Family trust
Why parents chose Combo.
Families usually want three things: a tutor their child respects, a plan that fits the real paper, and updates that make progress easy to follow.
Handpicked tutors
We shortlist tutors who know the curriculum, teach clearly, and can coach the exact exam habits that lift marks.
Top-university academics and exam-savvy specialists.
Clear weekly updates
Parents see what was covered, what improved, and what needs attention next, so progress never feels vague.
Structured feedback after every lesson block.
A plan built around your child's paper
Sessions are matched to the student's board, tier, topic gaps, and exam timeline instead of generic subject tutoring.
Board-specific support with a measurable target grade path.
Questions families ask before starting.
Do I need to know Python for IGCSE Computer Science?+
For Cambridge 0478 and 0984, pseudocode is the required language for programming questions. However, learning Python alongside pseudocode is strongly recommended as it helps you test your code logic. For Edexcel 1CP0, Python is the primary language. We cover both.
What is the pre-release task on Cambridge 0984?+
On the updated Cambridge syllabus (0984), Paper 2 includes a pre-release scenario provided weeks before the exam. Students analyse the problem in advance. We use the pre-release to prepare structured solutions and pseudocode so students arrive fully prepared.
Is data representation difficult?+
Data representation (binary, hex, denary conversions, two's complement, ASCII) is one of the most predictable sections of the exam. With the right method — which we teach — it becomes one of the easiest sections to score full marks on.
How are trace tables marked?+
Trace tables are marked line by line. Students must show the value of each variable after every step. We practise the exact layout Cambridge expects and work through progressively complex algorithms until the process is automatic.
Can you help with networking and cybersecurity topics?+
Yes. Networking, internet protocols, cybersecurity threats, and data protection are significant sections of the theory paper. We cover all key definitions, explain how protocols work, and practise the application questions that often appear in Paper 1.
