Work through single- and multiple-choice questions, then read the explanation for the answer and each option. Choose all, unfinished or wrong questions; shuffle questions and choices; use a study timer; and resume where you left off. 3. Review mistakes and uncertain concepts Collect questions marked for review, recent errors and repeated mistakes. Filter by cumulative wrong-answer count and focus on weaker domains or difficulty levels. The glossary report connects your known/not-yet records with accuracy on related questions. 4.

Afterwards, see correct, wrong and unanswered counts, your score and domain results, then revisit mistakes. Tools that fit your study routine Optional audio study reads terms and meanings aloud.
