woth it to retake Statistics for sole purpose of CRNA?

Hi!
I just got into Nursing school

I'm not sure what specialty to go into yet, but I am leaning towards CRNA.
I shadowed two CRNAs, and it was a great experiance!

So I was wondering about CRNA prereqs--since I have time next semester to take some classes, and I start sighning up in only a week.

I know that statistics is a CRNA prereq. I took it before, and got a "B." Since next semester is the only time I will have extra time (based on how the nursing curriculum is organized) to get some pre-crna prereqs out of the way, I was wondering if I should retake Statistics so I can get an A. Or is it not worth it since it's only one class? I noticed on some schools they want my statistics grade listed, among ochem and biochem. Although, it won't look like a retake becuase my school just re-organized the math department and the statistics course was previously under "health sciences" is now a different name under "mathetmatics department"--not that it would really matter I guess lol.

I've already gotton all the other prereqs like ochem, physics, etc out of the way.

SHould I pool my time into retaking that class or is it really not worth it?

thanks!!!
