If you have trouble viewing these files, try the following troubleshooting tips: First, make sure you have Adobe Acrobat installed on your computer. Open Acrobat, and click “Edit”, then “Preferences”, then select “Internet”. Make sure the “Display PDF in Browser” box is checked. If that doesn’t solve the problem, click the "MS Office" icon (shown directly above this paragraph) that says “Click Icon to view Study Guide in MS Word format”. After clicking this icon, the "Study Guide" page will re-load. Once it re-loads, clicking on each system tab will display the material in a “.DOC” format.
