UK Specialists for International Students
Expert IGCSE Computer Science tutoring online
Looking for an IGCSE Computer Science tutor online? Nexus Academy matches students with a UK-qualified Computer Science specialist for Cambridge IGCSE 0478 (or 0984) or Pearson Edexcel International 4CP0 — one-to-one from £14 per hour, with a free demo lesson and no lock-in.
Nexus Academy is a UK tutoring company, not a marketplace or platform. You are matched to one tutor for the international specification the school actually enters — not a UK GCSE J277 teacher handing over GCSE papers, and not a directory of profiles.
Cambridge 0478 is two equally weighted papers: Computer Systems, and Algorithms, Programming and Logic. There is no calculator. Paper 2 includes a scenario-based programming question that students who only memorise theory cannot bluff. We diagnose whether systems recall or Paper 2 logic is leaking, then practise that paper in the timezone the family actually lives in.

The Challenge
Why IGCSE Computer Science is harder than “doing GCSE papers”
UK GCSE Computer Science past papers are the wrong revision pack. Cambridge 0478 uses its own paper shape, pseudocode conventions and a 50/50 systems-versus-algorithms split. Students at British-curriculum schools outside the UK who download OCR J277 papers train for an exam they will not sit.
Paper 2 is half the qualification.
Cambridge 0478 Paper 2 (Algorithms, Programming and Logic) is 1 hour 45 minutes and 50%. Scenario-based programming, logic gates, and trace-style questions sit here. Theory-only revision leaves half the IGCSE unprepared.
0478 and 0984 are the same content, different grade scale.
0984 is the 9–1 version of 0478. Content matches; you cannot enter both. We confirm the syllabus code so reports and past papers use the correct grading conversation with parents.
English as the language of the paper, not of conversation.
Command words, precise technical terms, and writing a logic explanation in English cost marks for bilingual students even when the programming is sound. We mark language the way the mark scheme does — terminology, not fluency coaching.
Our Approach
How Nexus IGCSE Computer Science tutors work
The diagnostic confirms 0478, 0984 or 4CP0, the exam series (June, November, or March in India for Cambridge), and whether Paper 1 systems or Paper 2 algorithms is the weaker half. Timezones are agreed in that session — evenings UK time for the Gulf and South Asia are normal for us.
Lessons follow the Cambridge topic order the student is actually in at school, not a UK academic year. Paper 2 scenario practice is weekly once the programming constructs are in place. Logic gate symbols and the Cambridge pseudocode guide are taught as exam tools, not as computer-science trivia.
Parents get a monthly note in plain English: which paper, which topics, what to practise. WhatsApp remains the practical channel for international families after the lesson, not a substitute for the lesson.

Syllabus Coverage
Cambridge IGCSE Computer Science (0478) topics we cover
All content is aligned to the student's specific exam board — Cambridge IGCSE or Edexcel International GCSE — and their tier (Core or Extended).
Paper 1 — Computer systems
- Data representation: binary, hex, images, sound, compression
- Data transmission: packets, error detection, encryption
- Hardware: CPU, memory, storage, embedded systems
- Software: types, languages, translators
- The internet and networking; cybersecurity
- Automated and emerging technologies
Paper 2 — Algorithms, programming and logic
- Algorithm design and problem-solving
- Programming concepts: constructs, arrays, file handling
- Databases and SQL where on the syllabus
- Boolean logic and logic gates
- Trace tables, dry runs, test data
- Scenario-based programming questions
Cambridge IGCSE Computer Science 0478 — what is actually examined
Use the 2026–2028 syllabus. Paper 1 examines computer-systems topics 1–6. Paper 2 examines algorithms, programming and logic topics 7–10, including a scenario-based programming question. Both papers are 1 hour 45 minutes, 50%, no calculator. Nexus Academy confirms 0478 versus 0984 versus 4CP0 in the demo so we do not teach the wrong paper shape.
How the two papers split the syllabus
Paper 1 — Computer Systems (topics 1–6)
Data representation, data transmission, hardware, software, the internet and cybersecurity, automated and emerging technologies. Definitions must be Cambridge-precise. “Memory” as a vague word does not score; RAM, ROM and virtual memory have different jobs in the mark scheme.
Paper 2 — Algorithms, Programming and Logic (topics 7–10)
Algorithm design, programming, databases, Boolean logic. The scenario-based question is where students who can recite constructs still fail: they must design and write a solution for an unseen context, then consider testing. Cambridge publishes flowchart symbols, logic-gate symbols and a pseudocode guide — we use those documents, not a random YouTube dialect of pseudocode.
0984 is the same subject content as 0478 on a 9–1 scale. Do not enter both. O Level 2210 is a sibling syllabus — tell us if the school uses it; we will not assume 0478.
Where IGCSE Computer Science students lose the grade
Logic-gate diagrams with the wrong symbol or incomplete truth table
Cambridge specifies the symbols. Mixing ANSI/IEEE shapes, missing input combinations, or writing a Boolean expression that does not match the drawn circuit is a full-question loss. We drill the Cambridge symbol sheet until it is automatic.
Scenario programming that restates the story instead of designing a solution
Paper 2’s scenario is not a comprehension exercise. Marks are for inputs, processes, outputs, suitable constructs, and test data. Students who write an essay about the scenario score near zero.
Binary and hex conversion without showing place value
Same leak as GCSE, with no calculator to hide behind. Method marks need the working. We use 128–1 columns every time.
Using OCR J277 papers because they are easier to find
Wrong exam. OCR Exam Reference Language, paper timings and topic codes do not match 0478. Nexus issues Cambridge-style tasks, not leftover UK GCSE homework.
November series is a real IGCSE option — unlike UK GCSE Computer Science, which is summer-only. If the school is entering November, say so in the demo so the plan is not built around a June date.
Paper 2 question types we drill on purpose
Cambridge IGCSE Computer Science Paper 2 is where international students most often under-shoot their Paper 1. These are the shapes we practise, not generic “coding homework.”
Complete or correct an algorithm
Fill in missing constructs, identify the error, or rewrite a step. Students must use the Cambridge pseudocode conventions the paper expects, not Python-only syntax if the question is in pseudocode.
Trace / dry run
A table with identifiers and each pass. Skipping a row loses the question. We mark traces as strictly as the examiner.
Logic circuits and Boolean expressions
Draw the circuit from an expression, or write the expression from a circuit, then complete the truth table. Symbol accuracy is non-negotiable.
Scenario-based design and write
Unseen context. Plan inputs/processes/outputs, choose constructs, write the solution, then state test data. This is the question theory-only students cannot guess.
Cambridge 0478, 0984 and Edexcel 4CP0 — what parents should actually check
The school’s exams officer holds the syllabus code. Parents guessing from a textbook cover is how families buy the wrong past papers. Nexus Academy asks for the code in the booking form and again in the demo.
What Cambridge examiner reports keep repeating
Imprecise technical vocabulary. “The CPU is the brain of the computer” scores nothing. ALU, CU, registers and the fetch–decode–execute cycle are the words the mark scheme lists. We correct vocabulary live, not in a highlight colour on notes.
Logic and algorithms answered in vague English. Paper 2 wants gates, expressions, traces and constructs. A paragraph that explains the idea of a loop without writing the loop does not meet the assessment objective.
Ignoring the scenario constraints. If the question specifies a range check or a particular output format, answers that solve a different, easier problem do not get the design marks. We read the scenario constraints first, then code.
0478 versus 0984 versus 4CP0
Cambridge 0478 is A*–G, two papers, 1 hour 45 minutes each, no calculator, June and November (March in India). 0984 is 9–1 with the same content; availability depends on administrative zone; you cannot sit 0478 and 0984 together.
Pearson Edexcel International 4CP0 is a different qualification. Paper names, programming assessment and grade scale follow Pearson’s international GCSE, not Cambridge’s. We only use 4CP0 papers for 4CP0 students.
UK GCSE OCR J277 is not an IGCSE. International families should not be given J277 homework “because Computer Science is Computer Science.”
If English is not the language of the home
Nexus Academy does not turn Computer Science lessons into IELTS classes. We do mark the English the paper marks: command words, technical nouns, and short explanations of logic. Bilingual students often know the programming and lose the sentence that carries the mark. That is a Computer Science skill, and we treat it as one.
International Exam Board Specialists
Cambridge and Edexcel International — what we match
Cambridge IGCSE and Edexcel International GCSE have different specifications and mark scheme conventions. Your tutor knows both.
Cambridge IGCSE Computer Science (0478 / 0984)
0478 is graded A*–G. 0984 is the 9–1 version of the same content (not available in every administrative zone). Two papers, 1 hour 45 minutes each, 50% each, no calculator. Paper 1 Computer Systems; Paper 2 Algorithms, Programming and Logic, including a scenario-based question. June and November series; March series in India.
Pearson Edexcel International GCSE Computer Science (4CP0)
9–1 international GCSE with a principles paper and a computational-thinking paper. We do not hand 4CP0 students Cambridge 0478 papers and hope. The diagnostic confirms 4CP0 before the first paid session.
Cambridge 0478 — Paper 1 versus Paper 2
Paper 1 Computer Systems · 1h 45 · 50% · no calculator
Topics 1–6. Compulsory questions. Precision of definitions, data representation working, and network/security scenarios. Nexus uses Paper 1 to map content gaps before loading Paper 2 programming time.
Paper 2 Algorithms, Programming and Logic · 1h 45 · 50% · no calculator
Topics 7–10, including a scenario-based programming question. Logic gates, traces, algorithms, test data. This paper decides whether a student who “likes coding” actually converts that into an IGCSE grade.
Inside a Session
What a typical IGCSE Computer Science lesson looks like
Sessions are live one-to-one online, booked in the family’s timezone. A shared editor and whiteboard mean Python or Cambridge pseudocode is marked as it is written, with logic-gate diagrams drawn to the Cambridge symbol sheet.
A typical 60 minutes: a short Paper 1 definition or binary starter, a Paper 2 algorithm or logic task, then five minutes on the scenario skill that failed in the last mock. Students leave with one named Cambridge-style question, not a UK GCSE worksheet.
November-series students get a compressed calendar. June-series students get the two-year shape. We do not run both calendars as if they were the same course.
“The school in Dubai issued Cambridge 0478; a previous tutor had been using OCR GCSE papers. Nexus switched him onto Paper 2 scenario questions and the official pseudocode. He moved from a C on the mock to an A in June, and we could finally see what “algorithms” meant on the mark scheme rather than on YouTube.”
Common Questions
Frequently asked questions — IGCSE Computer Science tutoring
Nexus Academy offers an IGCSE Computer Science tutor online from £14 per hour for Cambridge 0478 / 0984 and Edexcel International 4CP0. Sessions are one-to-one with a degree-educated Computer Science specialist, a personalised plan, and monthly progress reports. There is no lock-in — cancel anytime after the free demo lesson. That £14 figure is Nexus Academy’s academic floor for IGCSE Computer Science, not a marketplace starting bid and not an agency rate of £50–70. You are matched to one tutor rather than browsing profiles. The free demo diagnoses the syllabus code, June or November series, and whether Paper 1 systems or Paper 2 algorithms is leaking, so paid sessions attack the marks that are actually leaking. Most families book a weekly 60-minute lesson through the exam year and add extra sessions before mocks. Compare that with typical UK academic tutoring around £35–45 per hour. Nexus Academy is a tutoring company: the price includes the lesson, the plan, and the reports, with no minimum block.
Nexus Academy is a UK tutoring company, not a marketplace or platform. We provide one-to-one IGCSE Computer Science tutors — and tuition — online from £14 per hour, matched to Cambridge 0478 / 0984 or Edexcel International 4CP0. The free demo confirms the syllabus code and exam series before any paid sessions. Parents searching “where can I find an IGCSE Computer Science tutor online” are usually comparing directories; Nexus Academy matches you to one specialist instead. Sessions run on a shared editor and whiteboard so Cambridge pseudocode, logic gates, and scenario programming can be marked live. Tuition can start in Year 10 or as a Year 11 mock-recovery block, including for British-curriculum schools outside the UK. Book from any timezone — there is no city page and no in-person office. After the demo you receive a short plan covering Paper 1 and Paper 2. Cancel anytime. The same £14 rate is on the pricing page, identical to the IGCSE Computer Science hire FAQ.
No. Nexus Academy does not treat Cambridge IGCSE 0478 as OCR J277. Papers, timings, pseudocode conventions and the 50/50 systems–algorithms split are Cambridge’s. Using UK GCSE papers is the most common wasted term we undo in the first month.
Nexus Academy treats 0984 as the 9–1 grading version of 0478 with the same subject content. You cannot enter both. 0984 is not available in every Cambridge administrative zone. We confirm the code so grade conversations with parents use A*–G or 9–1 correctly.
Yes, if the school enters that series. Nexus Academy builds November-series plans from the demo date; Cambridge 0478 is available in June and November (and March in India). UK GCSE Computer Science does not have a November sitting — do not mix those calendars.
Yes. Nexus Academy matches 4CP0 as its own qualification, not as “almost 0478.” Past papers, programming assessment and the 9–1 scale follow Pearson. Tell us 4CP0 on the booking form so the tutor is not preparing Cambridge Paper 2 by default.
Nexus Academy runs IGCSE Computer Science live online and books around Gulf, South Asia and UK evenings as standard. The demo agrees a recurring slot. WhatsApp is used for scheduling and short follow-ups, not as a replacement for the taught hour.
No. Nexus Academy treats Paper 1 as half of Cambridge 0478. Programming fluency does not replace data representation, networks or cybersecurity definitions. The diagnostic will say so if Paper 1 is the leak; we will not spend every hour on Python because it feels productive.
