It really does depend upon both the subject taught and the personality of the instructor. But if you are on a humanities track, there is a lot more emphasis on thinking and questioning / disputation (how well you argue your point), rather than giving the "right" response. It's good to ask advisors / guidance counselors, department heads, and other students about the teaching style of an individual professor, before you sign on to their course.
Although, I had one prof who required specific answers, AND he twisted the questions so you couldn't just reply what was on the study sheet. Maddening. But he ended up being one of my favorite profs, because of the great discussions we had when I went into his office to argue my case about why he should have given me more credit...
