Ugh I hate that. I got marked down a letter grade on a math test once for not showing enough intermediate steps even though my answers were correct. I also once got an answer marked wrong because the teacher couldn't understand my intermediate steps, even though the answer (and steps) were actually correct. When I showed him, he refused to change my grade. That was at University.
