When submitting a score a few question came up in my head, will the video be made public before the competition submitting phase is over? Will the code be?

Hi tr24em,
Sorry, that was our mistake - we had the competition set in the wrong submission format. You don't need to submit a YouTube video, but you do need to submit the code you used to achieve your score. If it's one file, you can submit the source file; if your code is in multiple files, just put them into a Zip file before submitting.

We've fixed our error, so you can submit your code by going to http://www.cs2n.org/competitions/vex-toss-up/submission/edit.

Sorry for the confusion,
--Ryan
