Has anyone here done the Canadian Open Mathematics Challenge? It's my first time writing it this coming Wednesday and I would like to do well. http://cemc.uwaterloo.ca/english/contests/open.shtml In particular, I was wondering how leniently they are marked. What kind of marks will I earn for lets say showing the initial steps in a Part A question, but not getting the correct answer? And, more importantly, how detailed should my solution for Part B questions be in order to earn full marks? The solutions they have posted are so detailed and well organized that mimicking them would eat away all my time.
