Things to brush up on before becoming an FNP so I wont be behind?

I am going to be starting an FNP program at the beginning of next year. I currently am and RN with my BSN and have been out of school for 2 years. I work as a clinic nurse in a rural health clinic. What kind of material should I brush up on before going back to school. I dont want to start out behind everyone who has been working in hospitals and other areas that would have more experience than me.


What materials would you recommend?


Thanks!
