Professor Drury is very clearly a highly intelligent man and a skilled mathematician. He seems, in fact, to prefer calculus to people...he is not very approachable and has trouble speaking on a first-year student's level. He's a good professor if you can speak his language, but if not, read the book and attend tutorials: TA's are more helpful.

Professor Drury is obviously a highly intelligent man, and quite passionate about what he does.

He is alright. Just an average, old professor. You have to read through the textbook prior to class, or the chance is you can't follow his lecture quick enough.

He made everything quite complicated. Also introduced things with concepts and knowledge we had't learned before. Also covered a lot of stuff way beyond the course. Using a projector to give the lectures by projecting him writing on papers onto the screen, but always forget to move the papers upward. You know what I mean.

He really knows the material above and beyond, and presents interesting and non-standard topics to the great pleasure of math-inclined students. He gives good advice during lectures on how to solve problems, but it is a good thing to read the textbook before class, or you will get behind in lectures. Exams are a bit difficult, but doable.

I am reading his lectures notes on his personal website. He is generous, because his online lecture notes are very clear. But, to me, it is a little bit difficult to follow.
