Really should use the textbook (a fantastic resource) more rather than seemingly teaching whatever pops into his head that morning, adding some much needed structure and predictability to the course. Cater to the lowest common denominator rather than the average (our class is very able, yet we go at a snail's pace because of a few) so most of the time those more able are bored or muck around. Can struggle to control the class at times. Overall, he's alright but certainly not the best ever.
