I can't imagine this isn't common in all facets of life. I always thought this would have been so easy for college exams to hire a ringer to take it for you, or submit assignments. Usually for the big lecture hall classes everyone would sit down, then just pass their student IDs to the end of the row, then a TA would walk up and down the aisles and collect them and take them back to sign in. It would have been so easy to just have someone else pass up your ID. Plus these would be critical classes, like your big core classes sophomore year where you want to have good grades for summer internships or maybe med school. When I took my GRE they also asked for ID at the testing center but just looked at it, they didn't scan it and verify it was legit. I could have just as easily been a ringer handing them a fakeid, something very easy to get at a college campus. I wonder how many people have done stuff like this and have gone on to reap the benefits.
