Discussion about GitHub Classroom on YC Hacker News

First of, there is a lot more to judge in a program than just the correctness of its output. Is the code readable ? Re-usable ? Did the student understood the core concept of the language and used them correctly ?

I saw some student fail to produce a correct program but had a well organized code. On the other hand, one of my student once created a program that was just made of switch instruction in switch instruction (up to 5 level of switches) and spread for more than 3000 lines, just because he failed to understand how function where working.
