Programming fundamentals — practice © Mr. JP McKenzie

Marks come from running your code against the test cases and from reading its structure — not from comparing it with the model answer, so any working method scores. Where the checker cannot recognise your technique but every test passes, the mark is still awarded and flagged in blue.
© Mr. JP McKenzie. Your code is marked on the server; the questions, test cases and answers are not held in this page.
Nothing about you is stored. You were not asked who you are, and the server keeps no record of your visit — not your code, not your marks, not the time you were here. It counts how often each question is attempted and what marks people get, and nothing else. Your own progress is saved in this browser only, so it is here next time on this computer and nowhere else.
