Question C1. I'm trying to take one of the quizzes in my class, but the quiz screen is blank.
Answer C1.

Question C2. I took a quiz and was able to scroll down until I reached question #10 and then I just couldn't go any further. I then removed all of the browser buttons and such (even my bottom status bar), but it just wouldn't go. I tried my optic mouse's scroll wheel, reduced text to minimal, stretched the quiz out as big as I could. No matter what I tried, I could not scroll down to the last question and the "submit' button." What do I do now? Answer C2.

Question C3. I sent a file to my instructor via the Drop Box or Assignment tool. However, my instructor cannot find the file and I won't get credit for the assignment. What is going wrong?
Answer C3

Question C4. I'm trying to take a quiz but when I access it I get a message that the quiz is already in progress. What do I do now? Answer C4
