It's a diet book for the most part and doesn't really have any memory or concentration "tips" in it other than when you get your hormones "cranking" you WILL think and concentrate better as a side benefit. It focuses on eating to maximize the hormones that keep you YOUNG and minimize the hormones that age you faster than normal. After going on the diet you'll notice you can study longer and generally have more energy for WHATEVER you want to do whether it's studying or PRing. When I go off it (like on long weekends or if I just get lazy with it) my ability to concentrate or focus on anything flops.
