The course materials on self-development program are available in two formats: video hosted on YouTube and Audio hosted in SoundCloud. In some regions sound cloud is not accessible. To check if this is the case for you, you can visit soundcloud.com and see if you can access their global page. If not it means it's not available in your region, so you should opt for YouTube video instead. In the event that the video can't be played, please check if you're using a compatible browser and try refreshing the page to re-establish new connection.
