About this Site

I started recording past paper question videos, for my own classes, in the run up to the 2024 exam season. They got about 5.5k views (now approaching 40k), which was a lot more than I was expecting. I've pulled together this website as a one-stop revision shop for N5 and Higher Computing Science, with video walkthroughs of papers from 2023-2025, along with two revision papers for each level (two N5 and two Higher) that I wrote as extra practice, since we don't have as many previous papers as some subjects.

In 2024-25, I recorded some puzzles and challenges to stretch the best programmers. They're called Adventurous Algorithms, and some of them include puzzles from my maths teacher friend Chris. There are videos and Python .py code files on the page here.
