For pset 6, I had finished everything else, and then realized that it (the speller) needed to be case-insensitive. I made the change and submitted without testing, confident that there were no bugs in my code. Later (about three weeks later) I checked my score and realized that I had gotten a 0. I quickly found the bug, and now I want to resubmit. Is there a way to do that?
Yes, just submit it again. No need to resubmit the form, just the code as per the instructions. It will be regraded.
