These are the scheduled lab times where you can get help and guidance.
Each lab is time-boxed to 10 hours in total - 1 hour for preparing, 6 hours for carrying out the experimentation and exploration, and 3 hours for writing your lab report. For each lab there is scheduled 2 hours in a lab room where you can get help and guidance to get started - for the remaining 4 hours of experimentation and exploration I expect that you will (like previous years' students) be able to manage on your own (following the lab instructions).
