You have the option to go to more classes than you expect to take. Some may turn out to be too much overlap with what you have, too high a level, or not really what you thought they would be. Easy to drop for 7 weeks but cannot add after 3 weeks. And it can be very hard to catch up if you were not sitting in on a class.
Course levels
5000 level intended for MEng
6000 level intended for PhD and interested MEng
