The reference materials are in Adobe Acrobat format.
In order to view and print the file, you must download a free copy of Acrobat Reader, if it is not already installed on your system. After you download the reader you must install it in order to view the study guides. You only have to do this once. Depending on your connection speed, it may take several minutes for the study guide to download and the reader to show the document in your browser window.
Due to the size of charts in these documents, it is recommended that you download them by right clicking and saving the file rather than viewing them in your browser.
