I love helping people, but some questions on here come direct from some exam paper or another. Ethically I guess it would be better to ignore them, but what do others think? How about a poll (don't know if I can start one on this forum or not)?
I wouldn't answer a question from a current exam but would have no problems answering one from old papers used for mocks. When I was teaching exams were held on specific days, everywhere, therefore there wasn't this problem. I think it is with the home learning and exams from home but it appears these are being phased out now with the on-line testing.
