Got thrown in at the deep end in my first year due to a sudden staff shortage - sole responsibility for a third year module (including setting the end of semster exam - argh!). It was utterly terrifying but eventually good fun, and people actual passed the module, so I must have done something right. Now I am a glorified classroom assistant on a first year research methods class (basically I get to do most of the marking - hoorah) and also about to start as a Open University tutor, which I can thoroughly recommend. Hours fit perfectly with study, the students all actually want to be there and the training and support is great.
