When taking an exam or quiz and an answer is selected using the cursor and then the up and down arrows on the computer are used to scroll the screen up or down the answer choice is changed by using the up down arrows. If the cursor location has been moved from the answer box then this does not seem to happen as readily. However, if you forget or do not move the cursor then the answer has been changed and the student may not be aware of the change. There should be some sort of safeguard to prevent the inadvertent or unintentional changing of test answers.
