I see no reason to believe that using a Trained #MOLE as a self-study aid is any more effective than using a web browser and a decent search engine. Or a Q+A site like StackExhange. But guess which one uses more resources to achieve that same result?
I'd go further and say it's less effective than working your way through HowTo books or online courses written by experienced educators, in collaboration with subject matter experts. Which can be as simple as PDF or a static website.
