Calypso Continuing Education courses work with most modern web browsers and operation systems. Our Recommendation: To get the best experience with our website and courses, we strongly recommend using Mozilla Firefox or Google Chrome. You can download either browser for free using the preceding links. Apple’s Safari browser also works well. Internet Explorer is supported, though some students have reported display issues when using it. It is recommended that when using Internet Explorer you update to the newest version available. Some of the additional educational materials available with our courses are supplied in PDF format. You will need a PDF reader, such as Adobe Acrobat, to view those resources. Acrobat Reader is free to download and install. An internet connection of 1Mbps (one megabit per second) or higher is recommended in order to view the Calypso Continuing Education Appraiser and Environmental courses. Slower connections may work, but the material may load more slowly and you may be disappointed with the performance. If you are having trouble viewing page and/or videos, we strongly recommend clearing your browser's cache, cookies, and history.
