Paper 2 - covers all 6 units from the component two section. I created and have been using with students for 2 years - students enjoy using them. Gives them a good start for making their own revision resources.

Recently remade for J277! I have created revision cards for all topics in the OCR Computer Science GCSE (J277). These are used by my current Year 11 Cohort, they have found them quite effective as support tools in lessons and revision at home. I allow students to use them whilst answering question in lesson so that they are focusing on exam techniques whilst absorbing the subject knowledge too. I have created a revision wall by printing each card in A3 and arranging it on the wall. Students can consult the wall if they are stuck. All the cards have been designed to be printed double sided on the short edge, This is so that the topic name is on the back. All cards are using the ‘OpenDyslexic’ font, this can be seen on the PDF’s. Formatting may differ on the publisher document if you do not have the font installed. This pack consists of the original publisher file as well as a PDF of all the cards too. I have also created a PDF of each set of cards that represent each separate paper of the OCR course. Enjoy! UPDATE# I have added the Pseudocode Programming Techniques page, to match up with the Question Cards

Computer Science OCR GCSE J277 revision grids for all topics of the course. Each sheet covers a different topic of the course and has a A3 template to print and give to students to fill in for their revision. Covers all topics for both Unit 1 and Unit 2.

DESCRIPTION Drawing on my experience as a student who achieved an A* in GCSE Computer Science, and who continues to study computing at a college level, with an extensive analysis of notes, mark schemes and examiner reports, I’ve created a revision booklet that cover every expectation for the Computer Science subject on the Edexcel (and some OCR) specification. These notes are presented in an easy-to-use revision note, then question format. Colour coding, diagrams and a simple layout makes learning easy. Having refined these over my final years in high school, I’ve seen first-hand the results they can achieve. I’m confident that they will be an invaluable tool to you.
