 Important Instructions for Taking Quiz

There are two kinds of questions those with circles in front of the answers and those with squares in front of the answers.  The ones with circles have only one answer.  The ones with squares can have more than one answer but might only have one answer. Lets say a question has 2 right answers and you check the correct boxes but you also check two boxes that are the wrong answer. You will get a score of zero on the question even though 2 of the answers were correct.
