I would like to submit pset0 but I cannot login; I receive the message that Email or password is incorrect.

I think that the link I am using is good and I'm pretty much sure I'm typing everything correctly. How can I submit pset0?

  • If you are sure of email id, then try passwords of edx.org and scratch.mit.edu in case you are messed up with all these passwords.

I had the same issue at the login creen saying my email and password were incorrect.

In my case, it was because I signed in to edX with my google account. Maybe it has issues calling up my account/password with the extra handoff to google.

What I did was sign up for an edX account (instead of logging in via google or yahoo). Fortunately, this was my first class so no big loss (except probably have to redo pre-survey). I got to the submission page fine this way.

There also did not seem to be an easy way to delete my google-based edX account (there did not appear to be an account settings page with delete account button) - so now there's two accounts hanging out there in the internet.

If I had to do it again, I'd sign up with an edX account from the beginning!

Hope that helps!!

  • It seems this problem is still there. I too have signed in with Google and am not able to log in. There must be another solution; I'd hate to use another email account for CS50! Jul 24, 2015 at 8:40

i was sure of my email id and my email password. but since it was not working i've found this workaround that can be useful to who can have my same problem. go to your edx profile and ask to Reset Password then follow their instructions. then use this new pw to login to pset0 submission. now i have 2 pw, one for my email account, another for cs50.
