Before you start

Multiple-choice questions have four options and one answer, or five options and two answers when the question says "Choose two." Performance-based questions give you a task with a dropdown for every row. After each answer you see why the key is right and why every other option is wrong.
Check each answer to see the notes before moving on. Checked answers cannot be changed.
