I've heard people say that Aaron is a real bastard, but it's not the case. He sets a standard and he expects you to meet it, if you're not lazy he'll move heaven and earth to make sure you get there too - you give him the time of day and he'll do the same for you. I really enjoyed the course and it's interested me in learning more about calculus and linear algebra (things I would NEVER have thought possible). Also, if you're lucky enough to have Iain as a tutor consider yourself very lucky, he's very relaxed and knows his stuff backwards. Treat this course (and those running it) with some respect and it'd be impossible not to pass.
