<p>I’d still ask if I were you. I’ve attended two semesters of college so far, and so far both semesters I had a B that, when I asked, turned out to be misgraded. The first semester I had professor misread an exam score of 101 as 61, and the second semester the professor forgot to add my extra credit points.</p>
<p>If you want to get results, phrase your request something like “I was surprised that I got a B, since I thought I was firmly in A territory. Did I do poorly on exam three? I’m trying to figure out where I went wrong”. This isn’t accusatory, nor does it make you look like one of those students who beg for a better grade, but it does prompt the professor to explain the grade in more detail, at which point you can catch if an error was made.</p>
