I'm certainly not/not going to be the world's most stellar programmer, but I have to look at the other people in my class who are obviously holding up the rest of the students through their complete misunderstanding of the material.
Sure there is potential in everyone, and most likely a career path for any number of variables involved in producing a quality software product. But when a person is taking their second class in a programming language, and you ask them to show you their switch statement, and all you get is blank stares, is it your place to think that they need to find something else?
Obviously this is all from my personal experience, and I don't profess to know all the answers. But, as a general question, how do you handle a fellow student who is obviously not getting the coursework, and if they achieve the same degree will lessen the effectiveness of said degree from the same institution?
