Welcome to AS Level Computer Science Revision

Hey there! I'm Aarush, a fellow AS Level student who, like many others, found myself struggling to organize and access comprehensive CS notes. I created this website to help students like us navigate through the AS Level Computer Science syllabus more effectively.

This resource compiles all the essential topics and subtopics in one place, making revision more structured and accessible. Feel free to use these notes for your studies!
