I took the course. I love learning and have been learning new things for decades and thought my techniques were pretty good. I'm a very fast learner. The course helped me more than I was expecting and my learning speed and ability to memorize noticeably improved. Especially with the foreign language I'm studying. And the theories around how the brain works were interesting. You're probably being a little cynical. ;-)

What's that foreign language and how do you study it? (If I might ask)
