This is somewhat of a strange question but, does anyone know what to do if the professor made a mistake and gave you an incorrect final grade? I just got my grades today for the fall term semester and I received a B+ in physics lab. However, I think there is a mistake with the scoring. My scores are as follows: 
Informal lab reports worth 60% 966/1000
Formal lab reports worth 20% 183/200
quizes worth 20% 98/100
In our university an A is >92.4%, A- is 90.0% - 92.4%, and a B+ is 87.6% - 89.9%. Since the grades are already in I don't know what to do. If this is a mistake is there a way that they can change my grade even though the final grades are in?

 ".  Maybe ask him how he calculated it (maybe he added an attendance grade or something) and what he calculated your total to be.  And then show him what you calculated.
