Yes, any question or flashcard can be flagged and viewed at a later time. All you have to do to "flag" a question is to click on the check box or the flag itself located in the grey image on your Q-Bank dashboard. Once you have "flagged" a item, you will see a check mark appear. Your performance statistics on the main dashboard and in the "My Performance" area will also show you how many questions and flashcards you have flagged at that time. You can then set up a session by selecting to only see items that have been flagged.
