Unfortunately, the setup I'm talking about is the norm these days. It's the MyLab and Mastering software offered by Pearson.

It doesn't just stop at physics. I've seen it used in math courses and economics courses as well.

Sometimes professors will setup the system so that you can redo the problem with different numerical inputs for the variables, and that approach is fine to me as it lets me learn through trial and error without negatively impacting my grade.
