Anxious over current grades. Thoughts?

I would like to major in marketing. I am focussing on the general ed classes with a mix of prerequisites.
University of San francisco Is a consideration as well as menlo college. Fall’15 is when I would like to transfer to these schools

I have 6 Bs and 3 Cs
B’s: Macro & Micro Econ, Calc I, English, Psychology and Biology
C’s: Managerial and Financial accounting, and college physics.
And a withdrawal from Calc 2, because It just wasn’t making any sense with the professor I had and a tutor.

I am REALLY frustrated that I ended with a C in Managerial Accounting. I was doing really well at first with an 88% on the homework, with a few I didn’t turn in due to other conflicts, 77 on the first midterm, 85 on the second and a92 on the third. but completely blew the final. I was dealing with a wicked headache and was not feeling well at all a couple days prior to the final. I don’t think I could have gotten an extension because it was the last day and I thought I could handle it.

Is this really bad? Is it worth retaking accounting?

Classes I am taking right now are just general classes, Art History Philosophy and Statistics, all of which are A’s right now after 1 midterm.

I should also mention that this is not the first time that I transfered. I went to Utah State University for one year to be a ‘professional pilot’ but a whole bunch of things in my life changed, however I am already a pilot and can fly professionally without an ‘aviation degree’ but a college degree is necessary to fly for the airlines. So I came back to CC. NONE OF MY CLASSES from the previous school are transferrable. NONE. So I basically started over. I should mention that my grades there were not pleasant either, I was just so miserable that I was not enjoying my classes as well as the social scene. I was on the serious edge of depression. I was glad to be away from home, but I have never felt so ‘unwelcome’ somewhere I was unfamiliar with that had such a large religious influence.

I am also taking creative writing for my second english class which is also an A right now.

ALSO, I am 21 and a flight instructor. I am working (flying) 5 hours every other day with my students at my local flight school.I am limited to flying 8 hours to be compensated, but it takes me at least an hour to prepare for lessons. I would LOVE to transfer out of state to washington or colorado but I have made so many valuable contacts that are too difficult to throw away if I were to leave California.

Any replies?
