CaliRN, what are you trying to choose between? CRNA vs. MSN in some other specialty? Repeat: all programs that prepare CRNAs have tough science classes. The difficulty of any MSN program depends on what you are getting your MSN in. My first grad degree was as a CV CNS. No basic science courses at all. Same for NP and CNM. The Education and Adminisitration MSNs certainly don't have the basic science courses.
I would say that the CRNA program is considered to be the most rigorous of any nursing Masters program. Everyone knows it to be 2+ years of grueling work. It is also the only nursing grad program that cannot be completed part-time.
It seems kind of late in the game for you to be having these second thoughts. Didn't you know before you applied to CRNA programs what the curriculums usually entail? Excela is front-loaded, so you will get all the didactics out of the way in the beginning of the program.
If not, here goes: CRNA programs are a *****, no doubt about it. Your life is consumed by school. You cannot work during school except very very parttime, if that. People live on loans, unless there is a full second income. Your kids/spouse see (alot) less of you during the program. On the other hand, the programs are only 2+ years. The vast majority of people who succeed say that putting up with the hardship was very worth it. Single moms with kids do it, moms with spouses and multiple little kids do it, people are pregnant/have kids during programs do it. But you have to know what you are getting yourself into, and especially your spouse has to understand what life will be like for the length of the program and has to be willing to fill in for you.
It is important for you to figure this out now, because it would be very wrong to tell Excela at the last minute that you are not going to attend this Fall. There are numerous applicants for every single seat in every single CRNA program, and every school has an alternate list so that there are no empty seats in August. But alternates need some forewarning. Meaning that if the school finds out on the first day of classes that you are not coming, then it is too late to fill in with an alternate. Which is a crying shame because someone would be denied a shot at becoming a CRNA. Someone who really, really wanted it, but who was an alternate.
having read all your posts about moving to PA, etc., I was really really surprised to hear second thoughts from you and am extremely curious as to what you are trying to choose between.
