Prophecy Health Testing

Hello fellow nurses, I am a new grad, passed NCLEX and now I'm off to start and well find my first job. I have an interview with a Pediatric facility that requires pre-employment testing before the interview. They are using Prophecy Health testing for the exam. I am nervous because this is my dream job and of course tests make everyone nervous. I will be testing in Pharmacology (I'm pretty confident with math) and then a PICU test. Can anyone recommend any good sites or resources with PICU nursing questions or study guides? I appreciate your help! =)
