Free online courses to turn you into an expert on virtual and augmented reality
Deniz Ergürel

Thanks for the summarization ! We develop VR apps and we usually make incompany workshops. We also recommend an O’Reilly book “Learning Virtual Reality” (although not free) which is great for introduction ! Unreal and Unity have both a great community, also great tool for learning. Also has some free courses that explore VR/AR contents.
