Becoming an RN

"I am thinking about getting an associate of science degree in nursing, and then taking the certification test to become an RN"

Good thinking.

"Is it ok to get a 2 yr degree in nursing vs a 4 yr degree?"

Yeah, it's ok.

"Will I be able to get a job as a nurse if I only go to a community college?"

I dunno. I dunno if you can get a job if you get a BSN, MSN, or MSNBC. Getting a job has so much more involved than just the degree you get.

"Is becoming an RN the best route to go in nursing?"

It's certainly a pretty good one. The best depends on you.
