I'm taking the course through edX and I've just received the grade for pset1. My grade was 0.39.
Although my code has no problems, when I check it with check50, I get error messages. But not for code issues, rather, for design issues such as requesting text or displaying information. But my program outputs well according to all inputs received.
So the question is, to get a 1.0, do I just have to make it pass check50? And if it's OK should I leave it?
