It says before you take the test that when you get your grades back that you will be able to go over each questions one by one. but i don't see that option when I look at the grade sheet they give you. help!

btw i did horrible on it

This happened to me over the weekend. Re-take the exam under "Tutor Mode" as opposed to "Test Mode"; you'll be able to check each answer/explanation as you go along. And no worries, it's designed to be indredibly difficult so that you sign up for the course ;)
