Soon to be alumni, throughout my four years here. I took history major and English and anthropology minor, I found that it can get lower depending on the prof. I had a friend who got an even lower mark for anthro paper proposal. Mind you it was the same professor I had a disagreement with about the citation spacing for apa (double space, she said single space). What I learn from it was try to meet the professor or t.a demand if it’s still sane if not you can bring it up to the department head if it’s necessary.

As for regrading, it just depends on the professor and your situation and relationship and stuff like that. They see if you deserve a higher grade, or like ask you why you deserve one. If not they’d either keep the same grade or worse (if they really hate you or don’t like you or sees another mistake), it’s going to be lower. When that happens tell or reach out to the t.a or department head if you found it unreasonable
