Nursing

I feel so behind, I’m 22 years old still taking my nursing prerequisites. I had to take anatomy and physiology 1 , 3 times before I passed with a B. I got a B in anatomy 2. I also got a B in my microbiology class. I’m currently taking chemistry and statistics but I’m passing both with a C. I haven’t taken my TEAS exam or taken Patho yet. My GPA right now is a 3.0 which I know isn’t good. I just feel like I’m getting nowhere because I keep having to retake classes. Should I just give up.
