How this works
Practice or exam mode
Practice mode explains each answer straight away. Exam mode holds all answers until you finish, then shows a full review.
Shuffled answer order
Options are shuffled on every attempt, so you learn the idea rather than the position of the right letter.
Timer, flags and skips
A timer runs while you play. Flag questions to revisit them, or skip and come back from the question navigator.
