Hello! Some sample keys for the true or false three question test would be:
Keys are: False, False, False, True, True, True, False, False, True, True, True, False, False, True, False, True, False, True. False, True, True, True, True, False. Those are all the possible combinations for the answer key. (every 3 is a group). Hope this helps! Have a great day!
It depends on if you mean that they need to have a whole number or not, if not then they would not need any more because they would already have 1.5 packs. If they do need a whole number then they would need 0.5 more packs
