I'm hoping to start in August of this year should I get accepted. The last time I was in school was 29 years ago.
Like you, I'm scared and nervous; yet, like many things in life, it is an adventure. Adventures can be fun as well
What I've been doing to prepare is subscribing to different RSS (blog / blog-like) feeds from the New England Journal of Medicine, JAMA, Nurse.com news, NurseConnect.com (various areas), since I'm in PA - Pennsylvania State Nurses Association, RegisteredNurseRN.com blog, scrubs
I'm also reading what I can on this site as well as watching various Youtube.com videos on nursing.
Please note I cannot state I understand a lot of what I've read or seen; I'm just working on building up places for good information.
An example of what I did today, was start with http://allnurses.com/nursing-student-assistance/making-nursing-process-811862.html
Then look up Youtube.com videos that go over the various areas. I.e. Head To Toe Nursing Assessment - YouTube
-- good head to toe assessment video.
I've been using Evernote (there's a free version for various platforms including mobile platforms) to store what I've been collecting.
Anyway, turn your emotions towards passion for a worthwhile and fun adventure.
