Will this one grade end up f-in me or will a good response, i.e. I talked to the professor and she said that had I fully finished the fourth essay the grade would have been higher blah blah learning experience, help a bit?

Hey, Please let me know if I should be panicking. After the fall semester, I was probably around the top third, but this semester I made a bad grade in crim (I ran out of time), and I am now probably right at the median. I have NO interest in practicing crim, so it sucks that this grade was the kicker that brought down my GPA from a 3.420 to a 3.280 I did not get a C, (I got a B-) but it is my worst grade. I am not sure what the median is at my school (it is a top 20 program), since we don't rank. The top 20% cut if usually around 3.5. I really hate that I missed that 3.3 cutoff. Should I still apply to firms that have a 3.3 cutoff? Or what about firms that ask for top half? I have no clue how to do the math to calculate the median at the school, although I think it is a 3.2-something. I won't know if I made a journal until July. Ideally, I would like to practice in Austin, Dallas, or Houston. What do you older and wiser law students think?BTW: I am employed as a summer associate for 8 weeks at a pretty large firm.
