I took the hardest test since I got into college

And it was in an introductory Geography class with mostly freshman in it. The main reason that it was difficult was that there was no review sheet, he didn't really tell us what to study, it covered 6 chapters in the book, and out of the 75 questions on the test I wold guess roughly 15-20 of the questions ever came up in class. Most of the answers I did know I knew from high school or other college classes. I don't know if I passed it and I'm positive I would have failed miserabally if I had taken this test my freshman or sophmore year. I really hope he tells us the class average for the test, my guess is something around a 45-50.
