I've done a hell of a lot of revision today. In 3 different locations... all were too noisy, including the library.
This evening I shall go to the Arty Farty Library and try and work there. Surely people don't have to try and explain complex mathematic transformations in a loud voice there. Maybe the engineers and scientists who thought it was too load in the George Green will have gone there... to be noisy. I'll let you know. The view out of the window in the Hallward is a lot nicer, so that might be my downfall.
I hate revison.
