Submitting Projects
  - Create a .zip file as instructed in the Project
  description. Make sure it has the right files, right file names, and
  right level – typically files will be at the top level of the zip file,
  not in a directory in the zip.
  
 - Log into the online course site.
  
 - Use the Project tab and upload your zip file.
  
 - After a reasonable delay (depending on submission size and
  server load), you should get an “autograde” and comments to explain
  what was wrong if anything. 
  
 - You can resubmit up to the deadline (if any, and beyond the
  deadline if you wish to accept a late penalty).
