Thanks for the replies.
As I understand it though, Aerocourse doesn't actually provide any books to study with their guides? As in, it's just that, I guide where you find the reading material?
Culhane is complete as in you don't need to go buy additional books, but I heard not quite as good as Aerocourse. Is this correct?
Would anyone be able to reference some books (as in the actual reading material) as well? Thanks again!
