It is much harder than nursing school
. The time committment and more science is involved. It has to be done full time, no part time education available. Have to show up for clinical which is like a job in itself, and then you have all the classes and studying after that. Each program is a little differenet. Some let you out of clinical for classes, mine you went to classes after the clinical. finished up at 8 at night three days out of the week. Around three the others. Had to study and pre-op patients the night before if they were inpatient. Basically it is hard because of the massive amount of time and energy it will take up. It is definitely well worth it though. Just to clarify, when most crna's are asked if they would do it again- when they say no they don't mean they would not choose to be crnas. Just that it was so hard that they wouldnt want to re-live the experience. It is a great profession and well worth the effort. As long as your family is supportive you can make it.
Most RN's have a very poor understanding of basic sciences, they don't have to take the organic and biochem classes. And at many classes you take the same courses as physicians, dentists, optometrists, etc. Gross anataomy and patho classes I took were the same ones med students took. The anesthesia program I went to had twice the amount of semester hours required than the NP track. And we had way more pharmacology, anatomy and physiology, patho courses. I am a NP also, I would say it is much harder to do a crna program over a full time ACNP program. And none of the classes taken as a NP can transfer for any of the crna classes (depending on the school you go to a few may actually, but just the general courses). I hava MNA and has no relation to a school of nursing, so luckily had no nursing theory.
I got accepted into anesthesia school while I was taking organic chemistry, I dropped it as soon as I got my acceptance letter so I could take a short vacation before starting. Also, for people checking into programs to apply to--not all schools
are equal when it comes to how much of the sciences they want to teach you. There are programs where you need very little organic chem or biochem. Though it still looks really good on your application.
