I am starting my pre-reqs this summer at TVCC to become an RN. Afterwards I will start pre-reqs to get my BSN. I eventually want to be a CRNA if thats possible but I have so many questions about the classes i have to take like Statistics, College Algebra, Anatomy & Physiology, Microbiology, and Psychology. Everyone has told me those will be my hardest which I expected hard classes but are they too hard to pass? Or is it just a thing where if you study you'll be ok? I know this is probably a stupid question but i worry about not doing good in any of my classes seeing that I'm a straight A student in high school and don't want to fail a class that my parents are paying for me to take. Any information would be helpful and I'd be glad to hear what you have to say. Thank you, Whitb :)
