At the recommendation of this Forum I purchased the PR Book along with the Nat. Brilliance & Super Memory Tapes. The results were encouraging but not optimal. I have difficulty with the photo focus and accelerated learning states. While both time and money are scarce I need a tool to optimize my performance in an MBA program. For those who have made similar treks, is it better to progress to the course and guage impact or is my time and money better spent attending the class?
