Ya, me too. I had an assignment where I used arrays in solving the problem. I guess the class didnt cover arrays yet, and so I failed the assignment. The teacher has one solution that she was expecting to see, and when it wasnt that, I failed. So, I was somehow supposed to guess what they wanted to see for a solution in that class based on what was taught to that point. Granted, I wasnt really following the "lectures" at all. I'm pretty sure the teacher was basically 1 week ahead of the students, learning it herself.
