I was working FT too because we were told that having health insurance was a requirement for entry and to remain eligible to complete the program. Only to find out like over a year into the program that I was the only dumbass in the entire class working FT because everyone else gave fake insurance card or were on their husbands plans.

Still one of my proudest adult achievements making it through that grind while working FT. I'd study and take notes like 4hrs a night after work, sleep for like 3hrs, go to school, and repeat 5x a week. And somehow made it through in one piece.
I would imagine technology is gonna make studying a bit easier. I did this over 10yrs ago, so what smart phones are capable of doing should ease the burden. Plus Youtube videos on nursing weren't really popping like that back then, but it's a great tool for tutorials and discussion nowadays.
Your best bet though is to get organized. You're gonna have to develop great and efficient study habits because they cram so much info in such a limited time. Take personal notes on everything you read, I found it helps memorization and word/concept association seeing things in your own handwriting. Learn to use cue cards to help develop an understanding of medical terminology. Set up a comfortable study area and get familiar with Staples and office supply stores, lol. And it's not so much that nursing is such a complicated field of study. It's just the insane amount of things you're gonna be bombarded with in such a short time on top of all the classwork required. Maybe yours will be different, but I remember my pediatric clinical term paper alone was over 80 pages long WITHOUT graphs and inserts. I was a journalism/professional writing major in college and I think the longest paper I ever wrote back then was like 20 pages max. FOR A PROFESSIONAL WRITING DEGREE.
