Nurse's Drug Guide

If you are good at using the PDA go for it. I have a friend who used the PDA after graduating and she liked it better than the hard copy. Also, I know many nurses where I used to work, they use it all the time, and they get answers fast, plus I think the PDA has good learning tools, such as drug calculation and I think you have the option of upgrade.
I prefered the hard copy because I don't have a PDA. lol
As for advice on 1st year clasess and clinicals...study, study..and don't be scared is not that bad. Is just something new.
good luck
