Me. However, since grade changes now require authorization from the department head, I will only change grades for miscalculations; I won't consider subjective reasons. 

My process will simply be to see if the data was entered correctly on the spreadsheet and/or GET. If that's correct, I won't change your grade.

That being said, if your grade is way off from what you'd expect, you should email me. Use the email on the syllabus; don't use my private email if some of you should have it for some reason. I do not use that for official purposes. I will be monitoring my official email over the next few days fairly regularly. 

One other thing: do not make grade inquiries here; they are confidential.
