If you’re a student and you copy someone’s homework and turn it in as your own work, you are not only a plagiarist loser, you are badly failing to get the big picture of why we profs give homework in the first place. It ain’t for our pleasure or my health. It’s to prepare you for bigger and better things — like tests.
Consider the example of a homework problem that is worth 3 points. Say you decide you’d rather not bother learning the material or practicing the basics necessary to get the problem even half-right, and you just copy someone else’s work. All other potential worst-case scenarios — such as getting busted for academic dishonesty — aside, let’s suppose you get all 3 points on that exercise.
Then, a few days later, you take a test which contains either that exact same exercise or one basically the same as it — and it’s worth 12 points. The point values in the class are not weighted, so 12 points really is four times as much grade as 3 points. How do you think you’ll do on the test question if you didn’t bother to learn the material? Will you score more than a 9 out of 12? If not, you have earned a net loss of points. I’d say it’s extremely doubtful that you’ll get more than a 3 out of 12 on the test version of the same question, which means losing between 9 and 12 points as a result of the ill-advised decision to plagiarize. You steal a few points in the short term but lose lots more in the long term.
Plagiarizing another person’s work is not only dishonest, it is not in your best rational interest. So knock it off.
