Open-book questions are not really memory tests — they test whether you can find the right page quickly. These 10 drills give you a heading and ask which document and section it sits under, so looking things up under time pressure becomes automatic.

S2 is assessed by a theory test of 20 multiple-choice questions in 45 minutes. You need 16 out of 20 to pass. The app draws a fresh mock from this certificate's own bank each time and marks it against that pass mark.
Format described as published at the time of writing — confirm it with your assessment centre before you sit the test.
