CRNA here. GRE is a very small hurdle for a very rewarding and challenging career. I test well (although my grammar is shite), so GRE wasn't a problem for me. My wife (also a CRNA) who is way sharper in all things medical struggled with the GRE, but studied more and got her scores where they needed to be.
CRNA school is no joke, plan to put everything else in life on pause for 3 years.
CRNAs are the redheaded step child of the medical world. We aren't physicians, but I'd argue we are trained way differently and more thoroughly than any other provider aside from physicians.
The $ is great, currently a great job market, I can literally go anywhere in the US. Practice models and $ vary greatly by location. Want to live in a desirable urban area? = 50% pay cut and very little independence in practice. Like Rural living? = great $ and total independence in practice.
