Welcome to the second exam in the "Back to School with Ed Usset" series!! There are 6 questions to be answered and the answers and explanations will be given to you at the very end. You have exactly one hour to complete this exam. You may not use any other material besides your memory to answer these questions! No internet, no books, just what you learned from what Ed Usset taught you in his previous lectures and quizes. This exam will be avaliable for one week before it is archived. At that time, a new set of lectures and quizes will be avaliable from Ed Usset!Good luck!! :)
