Revision materials for OCR AS & A Level Computer Science.This is the old archive for these materials, for the new archive go to: https://archive.org/details/ocr-as-a-level-computer-science-h046-h446-revision-materialsThis is meant for students taking either the H046 or H446 qualification, by the way if you are taking the H046 qualification then these revision materials will not help you apart from a small amount of each of these units.These powerpoints and worksheets are made by PGOnline which is possibly one of the best study producers for this subject. There is also worksheets I have attached in pdf form alongside advanced notes which were written by Physics Maths Tutors which is another great study producer for Computer Science in general.I also attached some resources from mrfraser.org which is a very good resource for not only A Level Computer Science with OCR but also CIE and also good for GCSE Computer Science alongside teaching about programming languages like Python and such in general. To use mrfraser.org all you require is a college email address as it filters out regular email addresses and it will allow you to sign up and create an account from which you can access resources with. Alongside, there is a few things from TutorialsPoint which is another great resource for learning different programming languages, alongside cheatsheets for many different programming languages.This consists of Units 1-9 for Paper 1 and Units 10-12 for Paper 2 although there is also additional four units for the Programming Project being Units 13-16 (H446 only) although I do not believe PGOnline creates presentations for these units.I have also put in all of the examinations for the H046 and H446 qualification from the Sample Papers to the official examinations 2016 (2017 for A Level Computer Science, 2016 was AS only) onwards (except for AS Level Paper 2 2024 because I currently do not know where that is, A Level Paper 2 has been found).The current examinations I have in this archive are:2016 (AS Level was only examined this year, both papers and markschemes)2017 (AS and A Level, both papers and mark schemes)2018 (AS and A Level, both papers and mark schemes)2019 (AS and A Level, both papers and mark schemes)2020 (AS and A Level (both were cancelled but kept up), both papers and mark schemes)2021 (A Level only as AS Level exams were cancelled, but both papers and mark schemes)2022 (AS and A Level, both papers and mark schemes)2023 (AS and A Level, both papers and mark schemes)2024 (AS and A Level, AS Level Paper 1 and A Level Paper 1 only with mark scheme, A Level Paper 2 without markscheme)I have also attached resources such as books and tutorials which could be useful in the programming project or just in general to learn from for the qualification itself. I also have added the specifications, programming project guidance and also end of unit tests that I did which were also PGOnline sheets.I will update this as I get more materials for A Level Computer Science as I am currently doing the course and want to ensure that everyone has access to all the resources.
