Viewing PDF files
If you have trouble viewing an Exercise file or other document downloaded as a PDF (Portable Document File) file, you may need to download and install Adobe Reader to view it.
If an applet does not behave or appear correctly, click the RELOAD/REFRESH button, usually signified by an arrow or arrows on your browser (or press F5 on your keyboard if you are using Internet Explorer).
A useful website to detect Java on your browser is: http://www.javatester.org.
Adobe Reader is a free software program used to view PDF (Portable Document Format) files. Most WISE Exercise pages are downloadable and viewable in this format.
If WISE web pages do not load, try upgrading to the latest versions of one of these web browsers. These software programs are free.
