Proper use of brainwave entrainment programs

[Tigurinn]

I wonder if you can post up the pdf of the complete instructions for the Core States of Awareness Exploration Kit? I'm especially hoping for explanations, in layman's terms, of what Gamma, Beta, Alpha, Theta and Delta are supposed to do.

And one of these is supposed to help with learning and passing exams? (because the school sub didn't work for me)
