Curious about CRNA

Hi

I've been thinking about this profession recently after a "life" moment happened with me in the ICU last semester as a nursing student. Some stuff about me: I'm 22 years old, BSN student in my 3/5 semester graduating next year. I was the only student who got to rotate to the ICU in my clinical and taught me something important. I also volunteer in a sub-acute care unit if that helps since the staff there is so friendly.

I'm interested in being a CRNA but I have some questions

Do schools look at when you've completed CRNA prereqs (O-chem, physics,etc..) before you get a degree or consider post-bac work? If you take it before you graduate with a degree, will it help? I ask this because nursing school courses itself are already challenging as most nurses have experienced, and I'd like to concentrate on them if I can then focus on prereqs afterwards. This BSN will be my first BS degree. I haven't gotten the grades that I wanted in some prereqs though (Bs in pathophys, pharm and statistics) and I wasn't aware of the CRNA requirements until recently or else I would have known that I should have done better. Will this hinder me? What other factors will they look into? I understand that I'm still a student nurse but I'd like to see what I can do at this time to prepare myself in the long run.

Thanks in advance and anything helps! I've been quiet to the point where I feared getting help
