To answer a multiple choice question, click the circled letter to the left of the desired answer. The circle will turn blue indicating that it has been selected. Some multiple choice questions will have multiple answers. In this case, click the circle next to all answers you would like to select before proceeding.
One of the useful features of Examplify is that you can cross out answer choices. Simply hover over an answer choice and an X will appear on the right of the answer. Clicking the X will “cross-out” that particular choice. To undo this, click on the crossed-out text in the answer choice.
