With the internet, youtube, pdfs, software etc. i think it is possible but will depend on the subject matter and your access to equipment/resources, and your dedication and ability. I assume by yourself means you can interact with others online still.
But those sites or things can be fix to know who are you? But how fo others do to create study from their selves? You can also know your by your own way. You are you, you know who are you and also you what image can you represent at.
I can say that those are helpfuls but it is hard to study if you get resources from internets. Internet has a full of lies that you have met.
