ACNP exam materials- need guidance from my peeps!

Hi all!
I am getting ready to start studying for the ACNP exam through ANCC. I was wondering if anyone knew of any good review books, especially anything that might encompass the geriatric portion of the exam that they are planning to add in March I believe. A lot of the books I've seen are from 2010 and Im a little worried they are too outdated. Also, did anyone take the fitzgerald or barkley review courses? If so, can I get a rundown on how helpful you found them? I would love to talk with any new ACNP grads out there- we are few and far between!
Thanks!
