How is a student not hurt when given an incorrect assessment of their academic abilities?
Undergrad students? If it’s a CS class and not one of the intro to programming/algorithms ones you’re probably mostly checking if they read the book they were forced to buy (thanks ACM) so I would say it doesn’t really hurt them.
What schools do you have experience with? Also, never heard of ACM so I have no idea if that was used whatsoever for our classes.
