Unit 5 too." canonical: https://learn.modernagecoders.com/ccea-gcse-digital-technology-programming-help source: src/pages/ccea-gcse-digital-technology-programming-help.html --- > CCEA GCSE Digital Technology programming help in Northern Ireland: Unit 4 is written by hand, and the 2025 report shows where marks went. Unit 5 too. In short CCEA's GCSE Digital Technology (Programming) is three units: the compulsory core, Unit 1, a one-hour written exam worth 30 per cent; Unit 4, Digital Development Concepts, a written exam of 1 hour 30 minutes worth 40 per cent; and Unit 5, Digital Development Practice, a controlled assessment worth 30 per cent and 60 marks, completed in up to 36 hours in Python, Java or C# on a scenario CCEA publishes each June. In 2025 the Unit 4 paper carried 120 marks. CCEA's report on it says candidates predicted output well but lost marks on arrays inside loops, while loops, running totals and, above all, on not following the bullet-pointed requirements and given variable names, which it says align closely to the mark scheme. Modern Age Coders teaches handwritten algorithm practice against exactly those habits, the Unit 1 core, and the design, testing and evaluation skills Unit 5 grades, on our own briefs. We never work on a live controlled assessment task. The first lesson is free, then USD 100 a month in a group or USD 150 one to one. Start here ## Three courses for the programming route Two of the three languages CCEA allows in Unit 5, and the algorithms Unit 4 asks for by hand. Every card opens its syllabus.

Open the syllabus →](/courses/problem-solving-dsa-masterclass-teens) The Unit 4 paper ## Code on paper: what the 2025 examiners saw From CCEA's Chief Examiner's report on Unit 4, Digital Development Concepts, summer 2025. | Feature | In 2025 | | --- | --- | | Marks and time | 120 marks in 90 minutes, ten compulsory questions | | Question types | Multiple choice, fill in the blanks, closed response, tick box, matching terms and open response | | Marks per part | From 1 to 9 | | Extended writing | One question of 6 marks, marked in levels for the quality of written communication | | Share of the GCSE | 40 per cent | ### Where candidates did well Predicting the output of algorithms, identifying the cause of logic errors and writing accurate solutions, which the report says has improved year on year. Binary arithmetic, validation, test plans, and the difference between black box and white box testing, where many took full marks. ### Where marks leaked Arrays inside loops: using the index variable correctly, as in sales[j], and keeping a running total. Unbounded iteration, where many candidates reach for a for loop when a while loop is needed. Short explanations that describe instead of answering: what a constant is rather than why it helps, one point about a dry run instead of two, one difference between Unicode and ASCII restated backwards. | Topic | The slip | Practise | | --- | --- | --- | | Arrays | Not using the array name given, setting all elements with one assignment instead of a loop | Initialising and totalling arrays in loops, by hand, weekly | | While loops | Wrong condition, no counter moving through the array, output statements left inside the loop | Writing while versions of every for loop, and marking where each loop ends | | Constants | Defining a constant instead of giving an advantage | Answering "why" questions with a benefit, such as readability or easier maintenance | | Characters | Confusing the number of bits with the number of characters in ASCII and Unicode | Two genuinely different contrasts, stated both ways | | Sorting | Mixing up insertion and bubble sort | Tracing both sorts on the same short list until the difference is obvious | | Robustness | Naming a type of testing instead of the data used | Two of valid, null, invalid and exceptional data, at high volume | Source: CCEA GCSE Chief Examiner's and Principal Moderator's Report, Digital Technology, Summer Series 2025, and the CCEA GCSE Digital Technology specification, both from the [CCEA GCSE Digital Technology pages](https://ccea.org.uk/key-stage-4/gcse/subjects/gcse-digital-technology-2017). The 120-mark total is the 2025 paper's; papers can vary. The bullet-point rule ## The bullet points are the mark scheme The single most repeated piece of advice in the 2025 report, and the easiest to practise. Long Unit 4 questions set out a scenario and then list what the algorithm must do, usually as bullet points: read this, calculate that, output these two values, use one condition per if-statement. The report says of one such question: "These requirements align closely to the mark scheme." Candidates lost marks for not outputting a value a bullet asked for, for using two conditions where one was specified, and for entering numbers where the question gave variable names such as HireCost and NumberOfNights. ### Use the names given The report is plain: "where variable names are provided candidates must make use of them". A correct algorithm with invented names loses marks it did not need to lose. ### Show where loops end Outputs placed inside a while loop earned nothing when they belonged after it. Indent clearly or end the loop explicitly, so the logic is visible on paper. ### Count your ticks Where a question asks for a set number of ticks, "only the first n, where n=the required number, will be accepted". Extra answers in a single-answer space score nothing. The extended answer has its own trap. The report warns that "Candidates making use of generic terms will be unable to score in the top band", and elsewhere singles out words like faster and quicker. In 2025 the question asked candidates to describe procedural and object-oriented programming. Most described objects, classes and inheritance well and procedural programming thinly, sometimes as no more than step-by-step instructions. | Step | What to do | | --- | --- | | 1. Number the bullets | Write a small number beside each requirement before writing any code | | 2. Copy the names | Underline every variable and array name the question supplies, and use them exactly | | 3. Write the algorithm | One requirement at a time, in the order given, with loops clearly opened and closed | | 4. Tick them off | Check each numbered bullet against a line of the answer before moving on | | 5. Dry run it | Trace one set of values through by hand, which also catches outputs in the wrong place | Writing code by hand is its own skill. Students who only ever type into an editor that indents and completes for them find a blank page slow and untidy, and CCEA marks what it can read. We set handwritten algorithm work in every group from the start, alongside the on-screen programming Unit 5 needs. Unit 5 ## Unit 5: what the moderators noted, and where we stop Digital Development Practice: a new scenario each June, 60 marks, up to 36 hours, marked in school and moderated by CCEA. | Task | What moderators saw | | --- | --- | | 1. Design | Strong flowcharts and pseudo-code; user requirements sometimes copied from the task without being developed; user feedback to refine the design sometimes missing | | 2. Build | High standard of programs; every solution must be annotated; the strongest considered robustness | | 3. Test | Well-structured test tables, but extreme test data often missing; screenshots needed only to show corrective action, which some skipped | | 4. Evaluate | Too often descriptive; the advice is to judge each user requirement as fully met, partially met or not met, and to treat performance, robustness and refinements in depth | Two rules from the report shape how anyone outside the school should behave. "The use of templates is prohibited", and moderators encourage candidates to develop their own program style. CCEA also expects schools to practise on legacy tasks and practice tasks rather than rehearsing on the live scenario, and says "Extreme testing of data was lacking in a number of centres", a gap that practice fixes cheaply. ### What we do for Unit 5 Teach design with flowcharts and pseudo-code, validation and error trapping, annotated code, test tables with valid, invalid and extreme data, and evaluation against user requirements, on practice scenarios we write. Use Python or Java, whichever the school teaches. We have no general C# course; C# appears only in our Unity game course, so a family at a C# school should tell us in the first lesson. ### What we never do Look at, discuss or help with the live controlled assessment task, or any work produced for it. The teacher signs that the work is the candidate's own and may not correct it in detail for a fair copy. Supply templates or model solutions of any kind, which CCEA prohibits in any case. Unit 1 ## Unit 1, the compulsory core, in one hour Shared by both routes, worth 30 per cent, and broader than most students expect. Unit 1, Digital Technology, covers data storage and representation, networks, databases, spreadsheets, security, legislation and the wider effects of digital technology. The 2025 report found it answered well overall, with a few recurring gaps worth planning around. | Topic | What went wrong | | --- | --- | | Start-up | Many could not identify the boot-up sequence when a computer is switched on | | Databases | Validation questions separated candidates; many lacked the knowledge | | Spreadsheets | Some could not describe VLOOKUP, and some wrote formulae with the wrong symbols | | Connected devices | Many could not expand the letters IoT | | Legislation | Titles not known precisely enough to earn the mark | | Health | Answers not tied to the situation described in the question | Because at least 40 per cent of the assessment must be taken at the end of the course, schools plan when each unit is sat. For the step after the GCSE, [the CCEA Software Systems Development page](/ccea-a-level-software-systems-development-help) covers the A level, and [the Northern Ireland page](/coding-and-ai-classes-in-northern-ireland) sets out the two routes and the whole system from primary school up. Progression ## Four rungs through Years 11 and 12 Placement follows what a student can already write without help, on screen and on paper. | Rung | When | What should be true | | --- | --- | --- | | 1. Constructs | Year 10 or early Year 11 | Variables, constants, selection, for and while loops, written unaided in Python or Java | | 2. Arrays and algorithms | Year 11 | One-dimensional arrays in loops with running totals, bubble and insertion sort, linear and binary search, by hand and on screen | | 3. Data and testing | Year 11 | Binary, hexadecimal and overflow, ASCII and Unicode, validation checks, test plans with valid, invalid and extreme data | | 4. Exam habits | Year 12 | Long questions answered against numbered bullets, given names used exactly, extended answers in precise terms | ### Rung two is where 2025 slipped Arrays inside while loops were the weakest area in the report. Weekly handwritten practice closes the gap faster than anything else. The full order of topics runs down the [coding roadmap](/coding-roadmap). ### Rung four is quick to learn The bullet-point routine takes a few weeks of practice and then pays on every long question. Lessons lighten during controlled assessment weeks and before the exams. The catalogue ## Nine courses for the programming route Arranged by unit. The free lesson decides the first one.

Slots are fixed in UK time. After school Most Year 11 and 12 students choose this. Evening Around sport, music or part-time work. Saturday Long enough for a timed Unit 4 section and its marking. ### Handwritten algorithms Every week at least one algorithm written on paper against numbered bullet points, then marked the way the report describes. ### While loops on purpose Arrays processed with while loops as well as for loops, with counters and running totals checked by dry run. ### Precise words Extended answers rewritten until generic words like faster are replaced with the correct terms. ### Extreme test data Every practice test table includes extreme data, the gap the moderators flagged. ### Our own scenarios Unit 5 skills practised on briefs we write, never on the live task. ### Five to ten per group Students at one rung, swapping and marking each other's handwritten answers.

Ritu Kedia Parent Questions about CCEA GCSE Digital Technology ## What families in Northern Ireland ask ### How is the programming route assessed? Unit 1 is a one-hour written exam worth 30 per cent. Unit 4 is a written exam of 1 hour 30 minutes worth 40 per cent. Unit 5 is a controlled assessment worth 30 per cent and 60 marks, done in up to 36 hours. ### Is Unit 4 on screen? No. It is an external written examination, so algorithms are written by hand. In 2025 it carried 120 marks across ten compulsory questions. ### Where do candidates lose most marks in Unit 4? According to CCEA's 2025 report: arrays processed inside loops, while loops, running totals, and not following the bullet-pointed requirements or the variable names a question supplies. ### Which languages can be used in Unit 5? Python, Java or C#, chosen by the school. The solution must be written in one of the three. ### How often does the Unit 5 task change? Every year. CCEA publishes a new scenario-based task in June, worth 60 marks and taking up to 36 hours. ### What do moderators look for in testing? Structured test tables with valid, invalid and extreme data, both black box and white box tests, and screenshots only where they show a correction. Extreme data was often missing in 2025. ### Can a tutor help with the controlled assessment? Not with the task itself. The teacher certifies the work as the candidate's own and may not correct it in detail. We teach the skills beforehand on our own scenarios and never see the live task. ### What is in Unit 1? Data representation and storage, networks, databases, spreadsheets, security, legislation and the effects of digital technology. It is shared with the multimedia route. ### What comes after the GCSE? CCEA offers A level Software Systems Development and A level Digital Technology. Our Software Systems Development page covers the first. ### What does it cost? The first lesson is free. Then a single monthly fee in US dollars, lower for a group place than for one-to-one teaching, as listed in the fees section, with nothing paid ahead.
