Just wanted to clarify some things that may not be so obvious to everyone.
The quiz contains 50 Questions and Answers and is changed every month. The questions are presented 5 at a time and randomly with the Answers also in Random order. This means that every test and even the order of the Answers can be different for everyone. So, if anyone has a Comment about a Question please include the number. (example > 1.78 or 4.23)
After the first Quiz is taken you can take another with different questions until you have seen them all. It keeps track of which ones yopu've seen so that you shouldn't get the same Question twice. When all Questions have been seen there is an option to reset and start again.
The Page has been changed slightly to be more informative about these things.
