Former student here. I am very disappointed in the system for which you’re supporting. While I enjoyed most homework assignments, I especially enjoyed the P/F assignments (you either pass for turning it in, or fail for not turning it in). The P/F assignment were still graded for accuracy, though, so I was able to learn from them, too, but without the stress about negatively affecting my grade if I didn’t understand something. This is what I mean when I say ‘free point’ homework assignments, but I can only vouch for myself. During schooling, I used homework sites like Chegg (but not Chegg, because they suck) to check my answers, never as cheating. You saying that you’re disappointed in OP without truly understanding how they use these sites, is extremely disappointing coming from a (college?) professor. I expect better from both sides of the fence.
