I'm a student taking a statistics class way over my head. My professor is giving us homework questions over material not in the class, but he feels should have been learned in the previous class. I came from another school, so I didn't have that class, though I have the notes. The material he's talking about is not in there. So, even though, on my homework, I am getting the current materials right, its always predicated on some sort of calculations from the previous class that I'm getting wrong. I considered an online tutoring service, but the reviews were that of a scam, so I'm trying forums. Perhaps I can even answer some questions too--as long as it is not over the material that's causing my brain to ooze out of my ears.
