Actually this is not cheating. Cheating means copying somebody's content with or without his permission in an exam where this kind of information sharing is forbidden. In here, the lecturer specifies that information sharing is not forbidden. Therefore technically this is not "cheating". But it is wonderful to see when you remove the outside limiting factors and let the phenomena occurs in its own volition. Probably this will be one of the courses the participant students will never forget, instead of courses where you "memorize" everything until the last exam. Kudos to Mr. Nonacs.
