What’s your dream job? (Thanks for sharing!)

Saja works hard on a Homework Assignment and fills out the worksheet on her computer, typing her responses.  The instructions for this assignment indicated in all-caps in bold more than once that the responses must be entirely handwritten. The instructions specifically warn that any assignments that fail to observe this critical requirement will receive a zero. Saja doesn’t have access to a printer at home and it’s too late to go to the University to use their printer before the deadline. She doesn’t redraw the worksheet with all text and questions on a blank piece of paper, which would have been an acceptable solution. In a panic to meet the deadline, Saja doesn’t read the instructions before completing the worksheet. Saja is surprised and upset to see a “zero” in the gradebook. She finds out when she emails Professor Bohr why she got that grade, and explains she didn’t read the instructions. Saja argues it’s just not right for her to get a “zero” instead of SOME partial credit at the very least. She offers to redo the assignment, reading the instructions this time around. Will Saja’s grade change?
