I think it would help, especially, if you don't really have the mind for it.
A person with some basic design of experiment skills who reads some internet how to a new manual or two would likely know as much. That is work and class is easy though, right?
I'm home grow and would teach you whatever I know by PM or by post. There are many like me, but also a few trolls and idiots...you just have to be able to sort us out.
I typically tell a person my way, but know a few other methods I can explain, if you want to go that way.
