Brilliant Analytics
Not only do you get all the possible details about each question but you will also get intuitive and valuable reports that help you find weaknesses, identify patterns, and maximize your return on the invested time. Then, use the analytics to generate a custom quiz for you based on the questions you marked, guessed, failed, or taken over 3 minutes to answer, or all of the above.
In addition, each question has its own analytics and shows you details about your performance and also that of other test takers: question difficulty, % of users who marked it as a guess, % of users who bookmark this question, and % of those who found this question helpful to their learning.
