On a quiz, the question was "Il est_________ (It's ten past three o'clock)(Hint use the 12 hour clock) " I wrote Il est quinze heures dix. The only accepted answer was "Il est trois heures dix". There was no indication that it was supposed to be AM. Can you please either arrange to have it accept both AM and PM or at least indicate that you specifically needed AM or PM in the question.
Thank you!
