Create a Quiz in PHP

I'm looking for a quiz written in PHP. It should work the following way: 1. There should be 10 questions 2. Each question should be on a separate page (example : [login to view URL], [login to view URL] etc), so that when the user clicks on next, he will go to the next question and the last answer will be remembered 3. Below each question there should be two radio buttons with answers, YES and NO 4. After answering the last question the user should be brought to the results page. There should be only two results options. 5. The result should be calculated in accordance to the answers. Each answer should have the option to assign a weight between 1 and 10 6. The result script should be build this way, that I can adjust it later on. Example, if the user gives 10 yes answers, then the score is X but I can change it also so that when the user answer 10 times NO than he can also get score X. 7. The result script should have a description so that I know how to adjust it later on to my needs. 8. The result should be shown on a new page (example : [login to view URL])
