About MOP Review Tool
An unofficial review tool for MCAT Official Prep* (MOP)
This tool hides/shows answers for easy self-retesting. To use it:
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.
Keyboard Shortcuts
- Press '.' to show/hide answers for the current question
- Press 'q' to enter quiz mode (hides answers for every question)
- Press 'r' to enter review mode (shows answers for every question, like normal)
- Press 'h' to view the help screen, which lists these shortcuts
By default, every time you enter a question review session, quiz mode is enabled. To disable quiz mode (i.e., enter review mode), use the 'r' keyboard shortcut as detailed above.
