About the Author

Hi! I'm Oliver, a Computer Science student in the UK. I created CourseNotes as a way to share my learning and knowledge with the world, and help other students to do their best in their exams.

I am currently studying Computer Science at GCSE level with the OCR exam board. All notes on this site will be exam board specific, but a lot of the concepts are similar across other exam boards.
