grade report 的成绩就是你official transcrip 的成绩. Jan23 is the final grade you gonna get for your class, after that day, you can't argue directly with you Prof about marks, you will have to deal with faculty though. You should check with "grade inquiries" section for your primilinary mark, usually come out around Jan5th/6th. if you are not happy wiht the mark, u can go see the Prof and argue about it, and he has to change it before Jan 23rd. if you wanna argue, do it ASAP after you find out your mark, coz university system taking forever to change the grade.
