Click the radio buttons to select your answer to each question. Move to the next question using the ">> Next" button. You may hit the "< < Previous" button to return to previous questions, and reselect (i.e., change) an answer to that previous question. When all questions have been answered, hit the "Score Exam" button to see your results. If the message "There are unanswered questions." appears, use the "<<" or ">>" buttons to find the unanswered questions, and answer them. If all the questions have been answered, then the score is displayed, and the missed questions are listed. If you subsequently go back through the exam to work on missed questions, you can check for correct answers by hitting the "Score Exam" button again: If you now pick the correct answer the score should increase by +1.
