Taught live. First class free. In short OCR H446 has three components and no on-screen exam. Component 01, Computer systems, is a written paper of two and a half hours worth 140 marks and 40 per cent, and the specification says it "contains the majority of the content". Component 02, Algorithms and programming, is another written paper of the same length and weight, and it "relates principally to problem solving skills needed by learners to apply the knowledge and understanding encountered in Component 01". Neither permits a calculator. The programming project is 70 marks and 20 per cent, submitted as a portfolio in whatever language the learner or teacher picks. So exam preparation means writing code by hand and reasoning on paper, while project preparation means actually building something. We teach both. The first lesson is free, then USD 100 a month in a group or USD 150 one to one. Start here ## Three courses for H446 candidates Depth in a language for the project, algorithms for the papers, and the data work many projects turn out to need.

Open the syllabus →](/courses/full-stack-web-development-masterclass-college) Two written papers ## Nobody types code in an OCR exam From the Cambridge OCR H446 specification, version 3.0. Read the assessment column and the absence is the striking part. | Component | Assessment | Weight | What it covers | | --- | --- | --- | --- | | 01 Computer systems | 140 marks, 2 hours and 30 minutes written paper, no calculators allowed | 40 per cent | Contemporary processors, input, output and storage; software and software development; exchanging data; data types, data structures and algorithms; legal, moral, cultural and ethical issues | | 02 Algorithms and programming | 140 marks, 2 hours and 30 minutes written paper, no calculators allowed | 40 per cent | Elements of computational thinking; problem solving and programming; algorithms to solve problems and standard algorithms | | 03 or 04 Programming project | 70 marks, non-exam assessment, submitted by moderated upload or post | 20 per cent | Analysis of the problem, design of the solution, developing the solution, evaluation | ### What this changes about practice Eighty per cent of the qualification is written, so the decisive exam skill is expressing algorithms and reasoning clearly on paper, under time, without an editor to catch anything. A student who prepares by programming in an IDE all year and never writes code by hand will find both papers harder than their actual ability warrants, which is a preparation problem rather than a knowledge one. ### And the calculator note Both papers are explicitly non-calculator. Binary, hexadecimal, floating point and complexity arithmetic all have to be done by hand at speed, in papers already demanding on time. That is a practice issue with no clever solution: repetition from the first term, until the arithmetic stops consuming thought. Worth naming the contrast, because plenty of families choose a sixth form without knowing it exists. The other major English board sits its first A-level paper on screen, issuing a skeleton program in advance. [The AQA 7517 page](/aqa-a-level-computer-science-7517-help) sets that out, and the preparation the two boards reward is genuinely different. Source, read 20 September 2026: [Cambridge OCR Level 3 Advanced GCE in Computer Science (H446) specification](https://www.ocr.org.uk/qualifications/as-and-a-level/computer-science-h046-h446-from-2015/), version 3.0. Check the current version on OCR's site; your school will confirm which applies. Knowledge and application ## Component 02 is about using Component 01 OCR does not split theory from programming. It splits knowing from applying, which is a subtler division and one that changes how to revise. How the specification describes its own structure Component 01 "contains the majority of the content of the specification and is assessed in a written paper recalling knowledge and understanding". Component 02 "relates principally to problem solving skills needed by learners to apply the knowledge and understanding encountered in Component 01". ### So 02 has less content Its own content list is short: computational thinking, problem solving and programming, and standard algorithms. What it has instead is demand, because the questions apply material from the other paper. ### Which means order matters A student who has not secured Component 01 cannot really revise Component 02, because there is nothing yet to apply. Doing them in parallel from the start is the usual mistake. ### And synoptic is flagged The specification marks components 02, 03 and 04 with an asterisk for synoptic assessment. Questions can and will reach across the whole course. | | Component 01 | Component 02 | | --- | --- | --- | | What it rewards | Secure recall of a large body of content, expressed precisely | Applying that content to an unfamiliar problem on paper | | Highest-value activity | Spaced retrieval across every topic, all year | Unseen problems, solved by hand, then marked by a person | | Commonest mistake | Reading notes, which feels like revision and tests nothing | Revising it as though it were more content to memorise | | Handwriting matters because | Extended answers are judged on how clearly they are argued | An algorithm nobody can follow cannot be credited | The practical advice that follows is unglamorous. Write algorithms out by hand, every week, and have somebody read them who will say when they are unclear. That single habit improves both papers at once, and it is the thing students are least willing to do because typing is faster and feels more like progress. The underlying skill, predicting what a program will do before running it, is the same one the statutory curriculum names at school level, and it is set out with the research behind it on [the problem-solving page](/problem-solving-skills-through-coding-uk). The project ## Seventy marks, any suitable language, and entirely yours The project is where the programming actually happens, and OCR leaves the choice of language and problem unusually open. | Element | What it says | | --- | --- | | Weight | 70 marks, non-exam assessment, 20 per cent of the A level | | Submission | Component 03 by moderated upload, or component 04 by moderated post | | The task | "The learner will choose a computing problem to work through according to the guidance in the specification" | | Who chooses | A task "chosen by the teacher or learner" | | The language | Produced "in an appropriate programming language of the learner's or teacher's choice" | | The four stages | Analysis of the problem, design of the solution, developing the solution, evaluation | | Method | The specification notes learners may "include agile methods" | ### Freedom is the hard part Being able to choose any suitable language and almost any problem sounds like a gift and behaves like a trap. The commonest failure is a project too ambitious to finish and too vague to analyse, chosen in enthusiasm in September of Year 13. The marks are spread across analysis, design, development and evaluation, so a brilliant program with thin analysis scores worse than a modest one documented properly. ### What we teach around it Everything the four stages assume: interviewing a real user and turning that into requirements, designing before coding, testing systematically, and writing honestly about what did not work. And the habit of keeping a decision log from day one, because evaluation written six months after the decisions is reconstruction rather than reflection. Our line here does not move. We do not work on any candidate's project, we do not review it, and we will decline if asked. It is 20 per cent of an A level and it has to be the candidate's own. [The A-level coursework page](/a-level-computer-science-nea-help) compares where the marks sit at both boards, and [the page on declaring AI](/understand-the-code-dont-copy-paste-uk) explains why identified AI content earns nothing even when it is properly acknowledged. One useful consequence of the open language rule: a student can use the project to learn something their school does not teach. A candidate who wants to work in a language nobody in the department uses can, provided it suits the problem, and that is a genuine opportunity for a strong student. Progression ## Four rungs across the two years Judged by what a student can write by hand and what they have actually built, in that order. | Rung | When | What should be true | | --- | --- | --- | | 1. Beyond GCSE in a language | The first term of sixth form | At ease with data structures, file handling and objects in whatever language suits the project | | 2. Content secured | Across Year 12 | Component 01 material revisited by retrieval rather than by rereading | | 3. Algorithms on paper | Year 12 into Year 13 | Unseen problems solved by hand, clearly enough for a stranger to follow | | 4. A project that finishes | Year 13 | Scoped small enough to complete, with analysis and a decision log written as you go | ### Rung three is the exam Eighty per cent of this A level is written, so a student who only ever programs in an editor is practising for the smallest part of it. The sequence of topics past A level runs down the [coding roadmap](/coding-roadmap). ### And rung four is the trap Ambition chosen in September becomes panic in February. A project scoped to finish beats a project designed to impress, every year. We teach the skills the project assumes and never the project itself.

[Open the syllabus](/courses/python-ai-automation-masterclass-college) How lessons work ## By hand for the papers, for real in the project Teachers work from India on a clock that never shifts, leaving the UK five and a half hours behind from October and four and a half from March. Slots are agreed in UK time. After sixth form Where most H446 candidates settle in the week. Late evening Once training, a shift or a long commute is out of the way. Saturday or Sunday Room for a full 140-mark paper and then going through it. ### Algorithms written out By hand, every week, and read by somebody who will say when they are unclear. Both papers turn on this. ### Arithmetic without a calculator Binary, hex and floating point practised until they stop consuming thought, since neither paper allows one. ### Retrieval, not rereading Component 01 is a large body of content, and the only revision that works on it is being asked. ### Unseen problems Component 02 applies the other paper, so practice has to be on problems nobody has seen before. ### A clear line on the project We never work on it, review it or advise on its content. We teach the four stages it assumes. ### Groups by level Five to ten students at one stage, marking each other's handwritten algorithms.

The teachers are incredibly knowledgeable and passionate about coding." Ritu Kedia Parent Questions about OCR H446 ## What A-level candidates and parents ask ### How is H446 assessed? Three components. Component 01 and Component 02 are each written papers of two and a half hours and 140 marks, worth 40 per cent each. The programming project is 70 marks and 20 per cent. ### Is any paper taken on a computer? No. Both papers are written, and both are marked no calculators allowed. The only place programming happens is the project. ### What is the difference between the two papers? The specification says Component 01 contains the majority of the content and assesses recall of knowledge and understanding, while Component 02 relates principally to the problem solving skills needed to apply that knowledge. ### Which language is the project in? Any suitable one. It is produced in an appropriate programming language of the learner's or teacher's choice, which is more open than the other major English board allows. ### What is the project marked on? Four stages: analysis of the problem, design of the solution, developing the solution, and evaluation. A strong program with thin analysis does not score well. ### How is the project submitted? As component 03 by moderated upload, or component 04 by moderated post. ### How should a student revise the papers? Retrieval practice for Component 01 across all topics, and unseen problems solved by hand for Component 02, with somebody reading the handwriting and saying when it is unclear. ### Will you help with the project? No. It is 20 per cent of the A level and must be the candidate's own. We teach the skills it assumes and decline any request to work on the project itself. ### Should the project be ambitious? It should be finishable. Ambition chosen in September of Year 13 becomes panic in February, and the marks reward documentation as much as cleverness. ### What does it cost? The opening lesson is free of charge. Afterwards a place in a group costs USD 100 a month, or USD 150 for private teaching, taken monthly and never in advance.
