Lovely man. Great teacher, well respected amongst the lads.
Has a monotonous voice that can put u to sleep if you dont try hard to pay attention. But he has good ways of teaching and knows his stuff. Also a great house dean.
Genuinely gets the best out of his students. I have three Level 2 excellences to thank Mr Slack for. Amazing!
Probably the most down to earth teacher out there. Teaches in a way that makes you want to listen and doesn't miss a thing.
