Step-by-step walkthroughs of Cambridge IGCSE (0478) and A Level (9618) algorithms — pseudocode and real Python code synced line by line, with a live diagram tracking every step.
17 topics live: 7 free to try, no account needed, covering IGCSE-shared content (arrays, searching, sorting, loops, file handling). 10 premium A Level topics (linked lists, stacks, queues, binary trees, recursion, OOP, functions) unlock for a small annual payment.
Built out of my own classroom, teaching Cambridge CS. Students helping students understand the relationship between what the pseudocode says and what the code actually does. This closes that gap.
