Mr. Friedman is an amazing instructor. His vast knowledge is derived from actual working experience and provides “usable” information, not just an explanation of foreign theories. Upon returning from the Cat IV review session, I immediately began to use that which I had learned to become a better and more confident analyst. Alan is also enthusiastic, which helps keep his students focused on subjects that would otherwise seem dry and monotonous. Furthermore, he keeps the class engaged and works individually with each person to ensure that no one gets left behind. Because of Alan, I feel that I learned and retained more knowledge from 4 days of instruction than I would have from several months of self study.
