Definitely pay $4.99 for the GoodNotes app on your iPad. It's amazing, and I use it everyday for every class!
I second the advice about nursing books. I mostly buy an edition older, and I have never had problems with them. Just check with a classmates book to ensure chapters are the same, and, if not, figure out what the differences are to avoid confusion. This semester I paid $25 total on books. Seriously.
Find what works for you and fast. I spent too much time trying to figure out the best way I retain the material, but once I did figure it out, studying became a breeze (kinda lol). Try out several different studying strategies, and don't be afraid to seek out advice on how your classmates study, especially those doing well.
Don't consume yourself with nursing school. Take time for yourself. Sleep. Eat. Do things you enjoy. After school you will have to continue to so these things while your work, so start balancing your life now.
MOST IMPORTANTLY: don't be intimidated by all the horror stories and doom and gloom on this site, from other students, or anyone. You can do this, and it will be enjoyable. I'm a firm believer that life is what you make it, so go in with confidence and positivity and it will make a huge difference.
Let me know if you need anything else!
Good luck :)
