He presented RNA metabolism, translation and post-tln modification, which was fairly straightforward (LS2). His test wasn't too hard, a few strangely worded questions but you could get the gist of what he was asking you. His presentations are very thorough and he asks if there are questions after each slide. Sometimes he also forces people to ask questions to prove they understand, which is annoying because he'll wait till someone finally comes up with something redundant but I guess it sort of helps some people. He was very enthusiastic and friendly, though I never went to office hours. not too bad...
