I have seen a few posts about getting C's in pre-req courses. It's not the end of the world.
I got a C in my A&P 2 class. I thought my I blew my shot at nursing school. I was upset and depressed. I was wasting time worrying about a grade that I could not change.
AN helped me see that there was still hope and a C will not always ruin you.
You know what? I got into nursing school with that C!
Grades are important, but don't beat yourself up repeatedly because you got a C.
Work harder next time.
Remember, a C is a passing grade (just don't make it a habit if you can help it).
DON'T GIVE UP!
