We're working through the fantastic Haskell Programming from First Principles (http://haskellbook.com) book.
Each week before the session you should aim to read through the relevant chapters for that week and to attempt all the exercises. The session will be a chance to discuss what has given you trouble, compare solutions with others, re-attempt some of the exercises without notes etc.
People who started attending last year can carry on from where we were.
There was also a call for a second group last year so people are welcome to come and start from the beginning. There won't be too much separation between the groups but I want to make sure that everyone has a clear weekly target that they should be completing.
