Our video player automatically tries to adjust the video quality to your internet speed, giving you the highest quality possible but in certain cases, for very slow connections, this might not be possible. If you’re experiencing excessive buffering during playback, it’s probably because your Internet connection cannot support continuous playback of the video. In this case try to reset your connection/internet router or, if possible, try accessing your online courses using a better internet connection.   You may also want to try one of the following: 1. Close extra browser tabs or other applications that may be using up your bandwidth. 2. Make sure you're using the latest version of your browser.
