Hi, newbee here, can use suggestions

hello, i am new to this site, a 42 yr old guy, and just graduated a few weeks ago.
i am already employed as of 2 weeks ago, but that is a bummer....there were 2 positions at different facilities i wanted and i took the one i am at now cause i really needed to get back to work after taking a year off for the school. just my luck, the other 2 places called me within days after accepting the psotion i took, but i like it so far. working at a busy community health center with adults and peds, and feel i really learned alot and got into "work mode" very quickly....though i really wanted a position in a peds LTC, but they got back to me a few days too late .

anyway, i am awaiting my ATT and would like any suggestions for studying or what i can expect for the NCLEX-PN. i have the saunders book, and the incredibly easy book.
has anyone taken it recently? even though i am a grown-up man and have a family, i did this career change and i am feeling worried about passing.

i am open to any advice,
TIA
