  13. Bring to Lab and a few other things, see A205

  14. Why My Assignment Was Late • My scanner broke • I uploaded to a friend’s account • I can’t do PDF on a Mac • Network was down in my apartment • My laptop broke • I had an upload error • I had difficulty making a PDF • The internet where I lived went out • I did not start the assignment soon enough
