ACNP cetification

I recently graduated from the University of Texas Medical Branch in Texas Acute Care Nurse Practitioner Program. I have taken the ACNP certification exam twice and failed it by only a narrow margin both times. I am desperately in search of an ACNP that could help me get the edge to pass it. I am currently licensed to practice in Florida where you do not need to be certified, but in order to obtain a medicare number or work at certain hospitals I need to be certified. I am very frustrated because the ACNP program I went through only required 2 weeks of ICU, and instead I had 2 semesters of Internal Medicine. I feel like I know the content. My husband is a nurse and he can quiz me and I know 98% of the answers. I have ordered the CD and book from the ANCC for test taking techniques. I have also taken a 2 day live review course. PLEASE HELP, I NEED TO GET THIS PASSED. Anyone that can help me I will greatly appreciate it. Thanks G. Smith RN, MSN, ACNP
