Do you think I disagree with you ethically?  If so I am guessing you are not an English teacher. 

The system does what it does and questioning DOES get some grades raised.  There is nothing to be lost by this student in doing this for every single grade.  NOTHING to be lost. 

The education system we have today K-12 and University are honestly lost causes at this point.  Having hired engineers, programmers, marketers, etc. with degrees from very well known schools, I can tell you, a degree means zero to me at this point.
