Failing classes

Hi I just transferred to a college this semester and went from going to school full time to part time. It has been hard for me to find time and concentrate on studying because I work par-time. I can’t cut the hours because I’m supposed to work 25 hours a week. I think failed one or two of my midterms. The truth when transferred I just started a new major. I gone from being a fashion Design major which I was passionate about to a Business Communications major. Have anyone failed a class in college. How do recover that or how would bring up your grade after failing a midterm.
