I started the cs50x online course a few days ago and I've just finished my Scratch program for pset0. I'd like to submit it, however I can't find pset0 in the submission interface on http://apps.cs50.edx.org/cs50x/2014/@/submit (only psets1 to 8 are available).

Am I really too late? Is there any way I can still submit my answer?

Yes, you can. The final deadline is 31 Dec 2014.

pset0 isn't submitted through the submit page. The instructions are listed at the end of the pset.
