Do I have a shot at nursing school?

[Mommyfuturenurse]

Hello everyone I am a pre nursing student in california. Monterey county to be exact.. I was taking college courses in high school which I did average(b's) in except for history which I failed. Once I got into college I went back and got an A on it. I started off pretty good also getting an A in English and psychology.. And and a B in math.. I got to confident and thought I could handle taking a cna program, chemistry and math(I struggle so much with math). I ended up getting my cna license with flying colors but I got a C in chemistry and a D in math?. I went back an got an A in math and an A in biology(which I love). I'm actually planning on tutoring biology and/or English. So my question is how badly will this hurt my chances of getting into an rn program? Also if I keep working as a cna, begin to tutor for my college and keep getting A's do I have a chance at getting into nursing school? I have previously volunteered for a local hospital. Anything else I should do? Any advice thank you
