The grades are out of 1, so 0.21 means you passed 21% of the checks. In order to earn the certificate, you must get at least 0.60 (60%) on each pset and the final project. You can run check50 to check your programs before submitting and see your results. For example, in pset1, you have the mario check: jharvard@appliance (~/Dropbox/pset1): check50 2014/x/...

The gradebook is automated so there is probably no one there to look at your screenshot. If you want to put a screenshot online, as long as it is not a screenshot of your source code, that would be very reasonable (in terms of academic honesty). However, even if you have a screenshot of the "correct" program results, you still need to submit working code to ...

I found why grade were 0 in PSET2 ,it was all my mistake. Programs were correct, but the problem was i didn't have the CS50 appliance. So i didn't check the programs with checkCS50. I thought programs will be checked by humans. But it seems they are feeding it to checkCS50 and on results they are giving grades. So like i missed printing an '\n' at end of ...

Grades may take up to two weeks to appear. It is likely that your assignment was not yet checked. If you upload, wait two weeks. If you still do not have a grade, post on the reddit sub forum and Rob should be able to help you. http://www.reddit.com/r/cs50

Yes. You can resubmit as many times as you'd like before the December cut-off date listed in the Submit section.

I usually takes more than a week for grading to happen. Sometimes it might take even more than 2 weeks. So relax. If you have usedcheck50 and got all the parameters correct then rest assured that you will get full points for your submission. If this is the answer you were looking for, then please mark it as final accepted answer and have fun with the pset2....

If you are taking the class through edx.org, your score will be on a pass/fail basis. 1 means you passed and 0 means you failed.

Your grades should be available on your gradebook after linking your edX account. Head to https://cs50.me/gradebook, and link your edX account (if not already linked)!

Now all are correct. Solution: just wait some time :)

I think you have the same problem i had yesterday which is that I uploaded the first two programs hello and mario firstly then the third one greedy program then i have zero for the first two project and a excellent grade for the third one. the solution for that problem : uploading the all files for the pset1 on the same time with each other not separately ...

If it’s red it means you have not summited all the pset’s so you need to check which pset is marked as unfinished

Generally, you should be receiving grade feedback via email. Perhaps check your spam folders to make sure your feedback hasn't been directed there? If you can't find it, please send an email to certificates@cs50.harvard.edu with your details and someone can investigate.

One of your issues is you appear to be using the Harvard Fall 2016 problem sets, which are no longer active (and are for registered Harvard students). If you are an edX student, be sure you are using the edX materials found here: https://courses.edx.org/courses/course-v1:HarvardX+CS50+X/courseware Also, hello.c is no longer graded because the code is ...

It usually takes up to 2 weeks to view your grades. Same thing happened to me, and today I checked it was posted. I submitted mine a little bit more than 2 weeks ago. Give it a little bit more time.

It is very hard to say on the first glance, but have you done the "case sensitivity" portion of the pset? I had a problem there, which caused the same errors in valgrind. Mind you, that it is not so simple to use strcpy or tolower on word in check function.

I was facing the same problem(see my comment). I kept closing the window and doing it again till it showed up in the sidebar Also, you can click open the zip file from here itself and navigate to bounce.c to check it out

Not really sure this counts as an actual answer, but, nonetheless... Something similar happened to me with pset3. When in "CS50 Submit" page, I clicked "upload", selected the file, "OK", commented the version... So far so good... But, when clicked on "Start Upload", the page would just hang... So, couldn't help it, I'd click "Start Upload" again... < ...

From the Edx FAQs: any scores you received on past years' problem sets will (soon) be imported into CS50x 2017. (We’re still updating CS50x 2017’s gradebook.) However, moving forward, you must submit CS50x 2017’s problem sets, per the syllabus. So from now on you can only submit via the 2017 gradebook. However consider the two possible cases: If ...

Wow! I checked my account just now and my work have been graded!

If the fifth character of line is equal to ' ', return error?

What is the check50 2016 command? Even in 2016 I only see psets that have check50 that has 2015 as the year: check50 2015.fall.pset1.mario mario.c I think invalid ID means that the check50 line typed does not exist. And in regards to the 0 grade on hello and caesar. How long has it been since you submitted? Can I see the check50 output?


1

Did you submit all of pset1 at the same time and in the same package? If you submit them in different uploads, only the last upload will be graded and the other parts of the pset will get 0 or will not be graded. As for the mario grade, one of the tests actually failed. You should rerun check50 against the code that was uploaded. In fact, if you run your ...

You should be able to email rob@cs.harvard.edu about this :) Hope this helps! Thanks!

There are several things that could have happened. Are you sure that you uploaded the correct version of the helpers.c file? Did you compile or test using a different version? Usually, something like this results when an earlier version that isn't right gets uploaded in the zip file, or the zip file is created from the wrong directory. I would recommend ...

There have been problems with the servers over time. The error you're seeing indicates one of two issues - either your code won't compile, or the server is timing out (sometimes from excessive load). If it compiles cleanly locally on your machine AND you can get a clean check50 run from your computer, then it is usually server load. You should resubmit ...

For edX, you can ignore the "ungraded" tag in the top right. If your problem set shows a number next to it, that is indeed your grade for that pset. You have received a 1.0 (i.e., full marks) for problem set 1.

Grades you from 0, lowest, to 1, highest. You nailed it. I forgot the formula to determine the exact grade though.

As an edX-based student, use this link to access the gradebook, and then sign in using the same credentials you use to sign in to edX. You should then be able to click on the gradebook in the left-hand panel to view your grades.

Its name is grader, but this does not mean that it will assign you with grades like A, B, C ... The grader's feedback will be there in the CS50 Gradebook after a certain time. The feedback is in the range of 0 to 1. 1 represents all correct answers and 0 represents all wrong answers, and intermediate values point towards partially corrected answers. 0.6 (i.e....
