Questionaire! Question?

I have taken the questionaire a couple of times. And I took it today " Sunday June, 26,2011" at around 12 o'clock. And I answered all the questions right. And it told me I didn't pass. I know when you answer one of the questions and you click the wrong one it selects the right one. But when I clicked on the questions they stayed on those and didn't change to a different answer. So am I doing something wrong? Any help about this I would appericiate it.

Thanks,
