I also used to be very excited about online courses until I experienced them as superficial when compared to books and self-checks. I think the best way to learn some things ends up being experiential, so something more like an apprenticeship than a lecture would be the most efficient. But in reality, it seems hard to find that. You also find the same in, for example, college. Where a tutor may be able to get you up to speed faster by 'debugging' your learning.
