Binary and hex, representing data, logic gates, truth tables and logic diagrams.
Our own questions in the style of the exam, not past-paper questions. Questions from HL-only sections carry an HL badge: SL students can skip them.
How it works
Section A: 3 questions from every section, mixed together. Answer them all, then mark the section: you will see which topics to go back to.
Section B: a structured question about one situation, in the style of the longer exam questions. Write your answers, then mark them yourself against the mark points.
The questions are new every time you start. Nothing is sent anywhere; your best Section A score is kept in this browser.
