Requirements for downloading the video and running the app without heavy data usage.

While viewing course content on the app, you have the option to load the videos beforehand and then access them later.

You can use this feature to download videos while you are on WiFi so that you can access them later without spending significant mobile data.

However, even while accessing the videos later, you have to be connected to the internet in order to fetch quizzes and update your progress. Saving videos for later will ensure optimal data usage when you have WiFi access and when you are studying without WiFi access.
