National 5 Computing Science
Question of the week
Every week, one real question of the kind your child will meet in the National 5 Computing Science exam. Have a go (no account needed), then see how it is marked and why.
A car park counter uses 8 bits. 250 cars are inside and 8 more arrive. Why can't it count them?
This is what revision looks like on the course. Every topic in the National 5 course has a short note, a simulation to try, a practice quiz with feedback like this on every answer, and real coding lessons. You get a progress report for your child too, with a weekly email if you want one.
