Can you explain how the multiple choice and single choice questions work?

First of all, is the following correct? Multiple choice questions are where you can have more than one question correct and single choice questions can only have one question correct?

Am I doing something wrong? When I tried them, there doesn't seem to be any feedback when you click done. And, clicking on done takes you to the next page, so you don't know if you answered the question correctly or not unless you go back. Seems a bit awkward, is there a better way for me to handle this?
