There is no time limit while you take the quiz. If you can't finish the quiz in one session, you may want to save or print out the partially completed quiz for use next time because our server will not be able to remember your partially completed quiz. You must complete the quiz within one year from the date of purchase.

This could be caused by one of the following reasons:

1. Your computer's resource is low. In other words, you may have several applications running, and your computer may not have sufficient RAM to open another PDF document. In this case, we recommend that you first save the file to your computer by right clicking the mouse and choosing "Save Target As ...", and then open the file in Adobe Acrobat Reader.

2. You may not have Adobe Acrobat Reader installed on your computer or you may have an earlier version. Please click the button below to download the latest FREE version of Acrobat Reader.
