Bad Grade Junior Year

<p>I looked at my grades today and I got a C in one of my classes. I did okay in my other classes and had a 3.4, I don't want to think how bad this will bring me down. Is there any advice for this besides do better next time? I already emailed the teacher asking about my final exam grade, since I did very well on everything besides that apparently (or he just dislikes me, I can't say I like him either). I only have a year and a half left and this really bothers me. This will sound stupid and nerdy, but I have this sinking nervous feeling in my stomach that I just can't get rid of. :/</p>
