Dr. Khan’s lectures were made public for us (online) which made it very easy to listen and focus in class then go home and have notes at finger tips to study. I was not rushed to write everything down in class and could focus and asking questions which Dr. Khan encouraged. I also really liked how Dr. Khan called us out and asked us questions. It put us on the spot. Everyone was prepared upon next class in order to be able to answer. Dr. Khan made the class interesting.
