No. There is no argument that will warrant an increase in your grade. The grading system was explained to you, in writing, at the outset of the class, and you could have dropped the course if you weren't happy with it. The fact that you only belatedly bothered to pay attention to a policy that you claim matters a lot to you does not help your position. And you do understand that 2 different professors will have different sets of readings, lectures, assignments, and exams, so that it's possible that a student who earned an 85 in another professor's class might still have learned more than you did, right? You are no longer in the world of standardized testing. I assume you're not arguing that your grade should be reduced to a B for that reason?
It's highly unlikely your professor came up with this syllabus without someone higher up in the department or the administration reviewing it at some point. If he's been teaching for more than one year, it's even more unlikely you're the only student who's tried this gambit. Although frankly, he's probably not going to read any of your argument after you admit that you didn't review his policies until now. Take the B+ and make sure you don't end up in a situation where you have to wrangle over tenths of a percentage point next semester.
good argument, but its to the wrong person. its like asking a cop to tear up a ticket after they wrote it. you do have a good point, but i would partition the dean of that particular college....
Sorry, I think the professor has the final say and his reasoning is sound. Some professors just don't round up or down and there are usually no real rules that say they have to. I've had this happen to me before. He already said "I do not round up" and it was already explained in the syllabus so you should just take it. I know it sucks, but if you try to argue against him, he might lower your grade even more.
Your argument is incorrect. Professors are not expected to round up, and many will not. The professor is not submitting a numerical grade; they are submitting a letter grade only. If you want to argue that point, you would take it up with the committee in charge of writing the handbook, not your professor. I do not suggest pursuing this any further. He has made it quite clear that your grade stands.
