That varies from course to course. Some instructors may opt to allow for students to download their videos so you won't need internet to access them. The majority of the courses are not downloadable at this time. But we understand that this feature comes very handy specially for those working in remote locations such as offshore, or if you want to watch a video during a plane ride without WIFI. If the course is set to be downloadable by the instructor, there will be a link in each lecture that will allow you to do so. Soon we will also have a native app for your device where you will be able to download and store any course to be viewed without internet.
