I'm currently on Week 2, having completed and submitted all the required challenges for Weeks 0 and 1. I'm taking the course through edX, and I can't remember how I originally got to the page listing my grades (I had to take several weeks off and am only now getting back to the course), but I do vaguely recall a dark-red and white color scheme, and seeing all my submitted problems displayed with a passing grade.
Now it's been several weeks and I can only find this CS50.me gradebook page (https://cs50.me/courses/b90cbcd6-4c36-481c-8b6d-c6d50f4ed38e/scores), which looks completely different from what I remember. (Am I going crazy, or was there a design overhaul or something this last month?)
Anyway, the point is that I checked it last night and noticed that one of the problems I had submitted and received a grade for – the "hello.c" challenge, of all things – is now marked as "ungraded" (see screenshot).
And I can't figure out how to re-submit it! (Or if I even need to.) On the pset page (http://docs.cs50.net/2016/fall/psets/1/pset1.html) it tells me to go to "CS50 Submit" (https://docs.google.com/forms/d/e/1FAIpQLSdZ8iL3Ppd8YCXBRMvv0J8HActqo88Hk2IczhhLdhfpxnqSzg/viewform), but when I follow that link, it takes me to a completely unrelated page (something about "Visitas Puzzles"? I dunno...)
I also tried using the "submit50" command in CS50.io, but that apparently doesn't work for pset 1.
Very confused over here (and I'd still kinda like to know why my grade disappeared in the first place...) – I will be grateful for any advice!
