Almost all of us have been students at some point. How many of us peeked at the answer sheets when doing homework if they were available? On practice exams that had the answers following each question, how many of us looked ahead if we got a little stuck or unsure about how to proceed?
And when I took a higher-level calc class that did not provide the homework answers, I dropped it after a week.
And when I took a stats class that did not provide the homework answers, I attempted to drop it, until I realized it was necessary for my major.
The reason answers are put in the back is because teachers have realized over time that
without them, students don't learn as well, and they fail.
