Frequently Asked Question

All worksheets are PDF documents and you need PDF reader software such as Adobe Reader to open them.

If you have Adobe Reader set up on your computer but are still experiencing problems:

· Make sure you the version you have is the latest one.

· If you get a blank screen when trying to open a worksheet from the website, try refreshing or reloading the browser screen.

· Occasionally, a file may only partially download, in which case the PDF will not open. In this case, try to download the file again.

· Check that you are using the latest version of your Internet browser, as some older versions may have problems displaying PDF documents.
