Unsure of competitiveness

Hello everyone! I am a pre-nursing student--to make a long story short, I originally went to a university with a BSN program, the nursing program just recently underwent probation due to high % of students failing the NCLEX. I have decided to apply to an associates RN program then attend a RN-BSN program in my area (due to expenses) and due to a lack of stability from the BSN program. I am a nervous nelly and an overachiever, and nursing school grades/scores terrify me. I am still not sure if my grades or portfolio match up.

My schools do not offer an average GPA or average score on the Kaplan test/ATI-TEAS tests. My schools requires A&P I, A&P II, Developmental Psychology, Student Development in Healthcare, Humanities, and English Comp. My community college GPA is a 4.0 (A&P I, Orientation, English Comp), then a "B" and "B+" for my humanities and development psychology (from my 4-year school). I am taking A&P II over the summer, and cannot wait, as I LOVED A&P I, and did very well!

I also am pursuing my CNA, as well as phlebotomy just to make time go by! I have worked in a CNA position, minus certification, due to the retirement home's extensive training--and have experience with elderly with dementia and Alzheimers.

As of now, does anyone think I have a fighting chance with admittance? Obviously this will be a guess, as I have not completed my testing, but I am more concerned about GPA! I enjoy standardized testing and have been studying some time for completion of the TEAS/Kaplan in August/Sept.

My question remains--should I consider taking a humanities course at this community college, and then re-take developmental psychology due to the fact I only have a "B" and "B+" grade? I'm just terrified my grades simply will not match up, even into an RN program. Thank you to all responses!
