I am trying to upload my pset-4 to the cs50x 2016 gradebook but the upload seemingly takes forever. Kindly help me w.r.t. this problem. Thanks in advance.

  • Did you follow the submit instructions correctly? (Specifically the part that says you need to press "Start Upload" for it to upload the files in addition to selecting it from your computer)

Phew....Just got the upload right. I actually opened the zip file that I downloaded which was intended to upload only to find that the copy.bmp file in pset4/bmp folder was corrupt. Rectified the issue and downloaded the zip again and verified that every file was accessible or readable and uploaded it again. Viola!!!

  • Can you plz confirm me after how many hours your pset4 was graded cuz I too had some sort of similar problem and its been more than 24 hrs and mine is not graded as yet Aug 4, 2016 at 5:43
  • @FurrukhJamal It took approximately 9hrs for the pset4 get graded after the receipt of email from cs50x bot informing me that my pset4 was successfully uploaded. Aug 4, 2016 at 15:04
  • And did u uploaded it with all the recovered jpegs of recover or did u deleted them first and then downloaded the zip and then uploaded it? Aug 4, 2016 at 15:25
  • @FurrukhJamal I have removed the recovered jpegs because that would make the zip take around 35MB. So removed the jpegs (around 17MB after removing). Aug 5, 2016 at 9:58
