Hi there Dardie, I am planning to take the PSB test as well next month and I am out of school for more than 15 years. I have also bought the ARCO guide you referred to. I have 2 questions for you and will appreciate a response: 1) Is PSB for LPN is different from PSB for RN? 2) ARCO guide has separate study sections for PSB RN, PSB LPN and PSB Allied health. Did you study all sections to prepare of just the last section specific to PSB LPN? Thanks in advance!
