Can psets be graded a second time in edX?

Is it important or relevant to state something

need/want to up until the 31 Dec 2014 deadline.

It seems like adding in a deadline will make the submissions much more redundant.

    I'm unclear what you are asking. Answers to questions asked 4 years ago may very well be out of date. We have no plans to go back and close them. We're fairly sure that most students would understand that an answer referencing a 2014 date may not longer be applicable. – curiouskiwi Jan 31 at 7:41
  • The nature of the site (and all knowledge bases) is such that questions are supposed to be timeless. Otherwise I could resubmit that very same question again and no one would have any ability to duplicate it because it was simply asking the same thing at a different time. I would suggest checking out other sites on the network. – Evan Carroll Jan 31 at 20:26
  • This site is specific to a specific course. As such, questions may not be timeless since the course changes every year. I'm not sure what you are expecting. When that question you linked was asked, the student did indeed have until 31 Dec 2014 to resubmit. Are you suggesting the question shouldn't have been answered including that important detail? – curiouskiwi Feb 1 at 0:17
  • Yes, precisely. I'm saying to make that answer timeless it should point to a resource off site that either tells you how long you have to resubmit, or tells you how you can find out how much time you have to resubmit. Both of those improvements would make that answer timeless and valuable forever. – Evan Carroll Feb 1 at 0:21
  • How would that be timeless if the links would only apply in 2014? If someone asked that same question today, it would not be a good action to link them to an answer that only applied to the 2014 course (it's not just the date, but the actual answer that is outdated.) You seem to working on the assumption that nothing in the course ever changes. – curiouskiwi Feb 1 at 0:33

Answers should be timeless.

By timeless, I mean answers should NOT mention specific dates unless requrired. If they do mentions dates they expire,

The question,

Can psets be graded a second time in edX?

Is categorically "YES" and likely to remain that way in the future. What we don't want is duplicate questions, even if they're only duplicated once a semester, or once a year. What we want is to build a knowledge base that answers that question. Specfically for the above question the date could be removed, and you can tell the user where they can find a site that mentions

  • When they can no longer submit for their specific class. For this specific question you can find the end date by looking at the "Syllabus" when you log in to the course dashboard
  • How long you each course is, approximately from start until completion.

Both of these would allow us to answer that question once and for all with no further maintenance.

If someone asked that same question today, it would not be a good action to link them to an answer that only applied to the 2014 course (it's not just the date, but the actual answer that is outdated.) You seem to working on the assumption that nothing in the course ever changes.

No but I am working under the assumption that curiouskiwi♦ is not the primary source of information on this site. Where did you find out what date is the last date for submission for the user? Would it be possible to incorporate your method of acquiring that knowledge? If, not and things are really that specific to the class (which they shouldn't be), one option this site does support is tagging. Create a new tag for each class. On the tag wiki for the class you can specify the last date for submissions.

This stills makes the question timeless albeit by only off loading the parts that are temporal to a tag wiki. But in 5 years when people want more information about whether they can resubmit, your answer would otherwise be totally applicable.

Yes, you can submit as many times as you need/want to up until the deadline for the specific class you enrolled in. Each course has a date of open enrollment, and completion. After the course is completed you can no longer resubmit your work.

The specific dates for your class can be found on the tag wiki pages for respective class, such as .

Be sure if you resubmit, that you submit all of the programs for that pset, as they are graded as a whole. (In other words, if you need to resubmit greedy.c, you should still submit hello.c and mario.c with it at the same time.)

In the above sense we can put all of the temporal stuff in the tag wiki. If the argument is that this site is not timeless because of the class-semester nature, that would have to solve it.


tldr; time should not be in a question unless absolutely required.
