The Saunders Q & A is actually good. i learned a lot from that book. NCSBN is also really good. i actually read and tried to understand the lectures on NCSBN specially with Med surg.
basically, with my 2nd try i only used Saunder's, NCSBN, a Q & A book on prioritization, delegation and assignments and this book where it concentrated on SATA. i didn't even get any SATA on my 2nd take nor calculations. i guess the computer knew i am excellent in calculations. but yah i was worried why i didn't have a single SATA. i thought it was unusual. oh and btw, make your own notes for pharma. organize them. this helped me memorized meds since i was always stubborn to memorize 'em.
i stopped at 140 and i didn't know what to think but after a month of waiting ... i swear twas the longest month ever for me... i finally got the small letter =]
more importantly, pray. it helps.
good luck to all who will be taking =D
