Frustrated with the lack of a straightforward, to-the-point text book for this course (OCR GCSE Computer Science J276), I decided to compile the lesson resources that I have written over the past two years into this free eBook. Besides written content and diagrams to explain concepts, I have included links to many YouTube videos that will allow pupils to go deeper into topics and learn in ways other than just reading. You should be able to simply click on the image on all “Video” pages to link to the appropriate YouTube page straight from the PDF.

This is the first resource that I have published on TES.com so I would love to receive your feedback, particularly if find it useful or if you have suggestions for improvement. I have worksheets that I have written for each topic with this spec that I hope to upload in due course.

If you do find this eBook useful, you may be interested in my YouTube channel where I have produced a number of original videos to explain Computer Science topics as well as put together playlists of great videos from other YouTubers: https://www.youtube.com/mrawdimmick
Finally, if you are teaching GCSE Computer Science then you might be interested in my online Python course hosted on repl.it. As a “community” classroom you can point your students directly to it for some self-learning or you can “Import and Teach” the class into your own Repl.it Classroom for you to invite your pupils to join so that you can track their progress and provide feedback on their work: https://repl.it/community/classrooms/29589
