1) Filter questions that you would like to review using the MOP website. Open/enter the review screen which displays the content you wish to review.
2) In quiz mode, answers are hidden at first for every question. To view the answer, you can click on any of the answer choices or press the period (".") key.
3) Advance to the next question, either by clicking the navigation button or using the left/right arrow keys. In quiz mode, the answer choices for the new question will be hidden.
