This, of course, is the block I've opted not to study, so I am slowly reading through it without having to worry at all about doing a TMA. VERY, VERY interesting - although there are lots of bits that I would spend more time over trying to understand, if I had to answer questions on it afterwards! I think, personally, we should have to do all the blocks and all the TMAs.
