Hello all, I am trying to get into a nursing school in McKinney, Texas, and so far I have all my pre-req's except for Micro, which I will be taking in the Summer, and the PSB RN entrance exam. I have not heard about this exam before and am having trouble finding out any information on the topic. Apparently I only have one chance to take it in a 12 month period, so I want/need to be prepared. I hope there is somebody out there who knows about this exam and can help educate me on the subject. Thanks so much.
