Convincing Professor to Raise my Grade. HELP!!!

<p>Hey everyone, I’m new here and hope this is the right section. </p>

<p>Anyways, this past spring semester I’ve had CAP pneumonia, had a close family member die, and was prescribed Toprol-XL due to blood pressure from stress. I am part of the ROTC program at my school, which takes 10-15 hours of work a week here and work at least 20 hours a week at my part-time job. All of this combined has really hurt me this semester, particularly in Calculus. I am trying to get my professor to raise my grade, but so far have had no luck. Any advice?
If I can’t get it raised from a 54 to a 60 I am done and my life is ruined. I will either be stuck enlisting or working a dead end job for the rest of my life.</p>

<p>PLEASE HELP!!!</p>
