helps with studying

I purchased the digital download for help with studying. I am in college and like almost everyone find it difficult to study for hours on end. Since I have started listening to the BETA itsu I would say it has improved focus by about 50% as I am able to stay focused for longer periods of time. I have also noticed a little improved, maybe 20%, in my retention of information. Overall this has worked pretty well for me and I have already recommended it to a few of my friends. After reading more of this website I wish I had purchased the full set as it says the other CDs also can help with studying etc. Maybe they will be able to give my mind a little bit of an extra boost.
