<p>As someone who has taught at the college level, I am troubled by the idea that this proposed plan potentially adds up to a lot more work for the teachers. So little Bobby and 15 of his classmates failed Exam A, and want to retake it. Do they retake the exact same exam, or does Teacher have to make a new exam? Does Teacher have to make 15 new exams so Bobby doesn’t just fill in his mates as to what is on the retake? </p>
<p>Now Teach has to grade the retakes, which takes additional time. She/He also maybe has to spend time out of class reteaching Bobby and the Mates the material they didn’t get the first time - and they all have different schedules, so they are coming in one and one. Isn’t there the risk that the Teacher loses the benefit of teaching in bulk, as it were, and the class devolves into a Teacher tutoring 30 separate students all individually and all moving at different paces?</p>
