The course looks surprisingly good. The only problem I see is that this (because it is made in the Hive blockchain) is visible to everyone. It should only be visible to those on the course and only to those outside Hive. But that's not possible (yes, except in inleo if you pay for some special content). But I don't like Inleo by default because its front end doesn't support everything; I'm not even 100% sure you can see a YT video if you're not a premier member.
As a front end I would suggest ecency. Yes, I know there are some problems now but they will be fixed.
