Uh oh, did we make a mistake? Or perhaps you enjoyed learning something new! Good or bad, we welcome your feedback. Before submitting a correction, please consider the following:

Have you re-read the question to ensure you didn't overlook anything? Example: a question asking what is 'not' an example of something.
For brevity, we avoid adding clarification where we feel the intention is clear. Example: Which city has the largest population? We're looking for the largest of the four options, not the largest globally. Example: Which city is north of another? Choose the city that is due north over the one due east, even if the latter is a little to the north too.
Options can be eliminated if they are invalidated by the question. Example: We ask you to select the largest English city and we've included Paris in the options. That is a clue!
Have you done a quick search to confirm that your feedback is correct? You'd be surprised how many people don't!
Politeness goes a long way in encouraging us to consider your point of view.
