In general if you can get a respirator or at least an n95 mask if you still have them from covid(apparently that doesnt work); also make tries on an old book before going on the good one, at least if you mess up it isn't another hole punched in your wallet

He threatened you to either buy a new book or he would make your uni career hell, one of my mates did it, at the last exam he sent him back 5 times, the last time he went to take the exam the coordiator said "what else have you got to ask to him; he told you everything in your course; [insert name] give me the paper" he signed the paper and sent him off; the prof. Still gave him only 60/100.
