Hi nicole,
I def. wouldn't stop with Kaplan. The questions have alot of good content in their rationales and expose you to a broad range of material exactly like the NCLEX. I would not however limit myself to just Kaplan. I only did 50-100 q-banks a day. I also used Saunders, Lacharity, and Mosbys. Study your Meds by suffixes and Category and know those Lab values like the back of your hand.

hope this helps -Dave
