2 C's and 1 F...BUT I have 2 B's and 2 A's GPA is 2.53

Is this a bad GPA? Those 2 C’s were in Geology and Astronomy, I am about to attend Santa Barbara City College after being at Miramar here at San Diego, I am really worried right now, please give me some guidance!

Also I am hoping to graduate in a year.

Yes, that is a kind of bad GPA. It is a C-.
AWhy are you failing a class? Which class was it?
Do you enjoy Geology and Astronomy?
