Resources to prepare for BSN>DNP program

In my undergrad program pharmacology was considered the most difficult course, so to prepare for it I read the textbook and learned everything I could for months teaching myself the material on my own to make it easier (and it worked incredibly well)

I intend on starting a BSN > DNP program (likely FNP track) in a year, maybe two

And want to get a head start to increase my chances of success and retention, since its quite possible that I wont have as much experience as some of the other nurses.

Are there any resources/textbooks that anyone could recommend that I use to just start learning as much as I can, getting ahead?

I really want to put myself in the best chance to succeed, so if I can get an early headstart that would be incredible

Thank you so much !
