If I can give you guys only one advice it would be stick to UWorld and read the rationales! You learned everything you needed to learn in nursing school, UWorld will only reinforce it and make it so much more understandable! The rationales are very very in depth and very well written.
I took the 2 self-assessment exams and scored high on both of them. That really gave me the confidence I needed. Coming on here, and reading the success posts also motivated me when I was feeling down. Also, if you are a person of faith, PRAY PRAY PRAY!!! He will turn your struggles and worries into strength and comfort.
UWORLD and GOD is all you need
