To ensure you have understood the lessons and gone through the material thoroughly, we limited the number of times you can attempt a quiz.

Each time you come across a quiz, you will have two attempts on each quiz without any limitations. If you fail those two attempts, your third attempt will be 30 minutes after your second fail. If you fail for the third time, you can access the quiz once every 12 hours.

If you are locked for 12 hours, our recommendation is to go back to the lessons to ensure you will pass the quiz on your next attempt.
