I am creating a quiz in SharePoint(2010) that utilizes different lists in an aspx page.

When you select the "submit" button it sends your response to the answers list and sends you to the next question, upon completion it grades the quiz based on how many you answered correctly and what % you must get to "pass".

 Currently there are 10 questions, what i want is to have say 50 questions, only pulling 10 randomly each time the quiz is taken and still be able to calculate pass/fail based on how many questions you answered and how many were correct...

Any ideas?
