No. Components 03 and 04 are the programming project, marked by your centre and moderated by OCR. It is a piece of coursework rather than examined content, so there is nothing to recall.

The guide covers the two written papers, which are 80 per cent of the grade between them.

Yes. 13 topics for Component 01, Computer Systems, and 3 for Component 02, Algorithms and Programming. The full topic list is here.

None. OCR examines pseudocode on the written papers, and the guide follows that: the questions ask what a construct does, what an algorithm’s steps are and what its complexity is, rather than the syntax of a particular language. Your project language is your own choice and does not change any of this.

Yes, with 230 questions on Algorithms alone: linear and binary search, bubble, insertion, merge and quick sort, Dijkstra and A*, breadth and depth first traversal, stack, queue, tree and graph operations, and the Big O complexity of each.

85 questions covering logic gates, truth tables, Karnaugh maps, De Morgan’s laws, simplification, half and full adders, and D-type flip flops.

About twenty minutes for one subtopic, all three steps. Topics range from 41 questions to 230, so work by subtopic.

Write. Computer Science mark schemes want specific terms, and step 2 is where the difference between your wording and the printed one gets fixed. The method page sets out the evidence.

H446 is linear, so both papers are sat at the end of Year 13. The theory in Component 01 does not change once taught, so it rewards being started early and returned to while the project takes up Year 13 time.

Yes. The method puts the content into memory. Past papers train tracing algorithms under time, writing pseudocode to a problem and the extended responses. OCR publishes them free.

A PDF, emailed on purchase. The questions for a topic print together and the answers for that topic follow directly after them.

A PDF of 1,549 exam-style questions covering the examined content of OCR A-Level Computer Science, with the answers printed after each topic. It is not a textbook and it is not a coding course.

That is common and it is a risk. The programming project is 20 per cent of the grade. The two written papers are 80 per cent, and they are examined on recall of theory that the project does not practise.

There should be handwritten answers on paper and three passes over the same questions. The method produces two numbers each session, the first closed-book score and the third.

Not for this. The written papers use pseudocode, and the guide follows the papers. The language matters for the project only.

£9.00 for the whole specification. An endorsed OCR A-Level Computer Science textbook is usually £30 to £40.

116 subtopics at roughly twenty minutes each is about 39 hours for a full first pass, spread across two years.

Past papers, which OCR publishes free, and their own notes for anything not yet taught.

With Data Types and Number Representation, then Algorithms. Those two are 382 questions between them and they carry the most marks per hour spent.
