During my undergraduate university, the best scores had priority when choosing the limited slot numbers, including the time slots and sometimes which professor we were to attend. e.g. I would pick Calculus MWF mornings, group two because professor XxXx was in charge; lower grade students who polled agaisnt me would be bumped to a different group, or to a different time slot, or not making it to the lowest grade cut
