Numerical diagnostic
12 questions, 12 minutes for the whole set. There is no timer on each question, so you can move between them freely.
You can check your answers again before you submit.
A calculator is allowed, and there's one on screen. This practice checks how you set up each calculation, not your mental arithmetic.
