I got to go over one of my mid-terms, and my mark was fine, I got almost 90%, but one thing about how it was marked bothers me, way more than 2 marks should.

The final question on the exam was to state the year-end balance in two accounts. I did exactly what it asked for, and my answers were correct, but she gave me zero out of two because I didn't show her how I calculated it.

How can the right answer be a zero out of two?!!?!?
