Hello,
Couldn't you use the Geek Article System for that? You could create new "Lessons", and add them daily. I know that with vBadvanced, you can create a recent articles module. If you set permissions for only those people taking lessons, they would only be the ones that could see the most recent lesson, and therefor they would be taking the class. Others are oblivious that the module is even there. If the articles forums were hidden, and only showed to those people that have the permissions set, you could create a school within your site just for those students to see. Run that over once and see if that would help resolve what you are trying to do.
