The Natural Brilliance Home Study does not contain more information about direct learning and syntopic reading. In fact it doesn't come with the Natural Brilliance book, either. That said, I absolutely loved the home study (which helps you resolve paradoxical problems, pull out stop signs, and release your true natural brilliance).
I don't know of any other source besides the pages in the Photoreading and Natural Brilliance books (except maybe the Photoreading seminar).
