All modern computers should work fine on our platform, though we recommend having at least 1 GB of memory/RAM. We also do our best to support recent versions of the most common web browsers. Currently, these are the browsers that meet our requirements:
Google Chrome (newest)
Note: Ubuntu users may have to install the chromium-codecs-ffmpeg-extra package to make the videos work in Chromium.
Note: The video speed change feature for lecture watching is not yet supported in Firefox.
Internet Explorer (9 or newer)
If you are using an older browser, please try upgrading or switching to see if that improves your experience.
If you are accessing our site on a mobile device (Android / iOS), please note that not all site functionality is currently supported: for example, you might run into issues submitting peer-graded assessments, or in-video quizzes. Signature Track assignment authentication is not supported on mobile devices, so if you are taking a course in the Signature Track, please be sure to submit your assignments from a real computer. This is an area that we're actively working on; we apologize for the inconvenience, and appreciate your patience.
