The scores posted below are your accumulative scores for October and November. The problems were hard but we received many clever solutions. Some of you tried to solve the Friday-the-13th problem by looking at next year's calendar. Shame of you. Actually, that is good thinking on your part, but it wasn't what we had in mind ! We were looking for a logical strategy whereby you could learn something about our (Gregorian) calendar.
