Is it wrong to use or find these? And I'm talking about all the solutions. Of course, if a student were to come across this and copy the work down merely to get a good homework grade, that would be evident come exam time. However, if the solutions were used to better understand the material and to see worked-out problems, that could aid in learning. I'm just curious what you think, particularly professors. Admittedly, I'm facing this somewhat self-imposed ethical dilemma.
