PSB practical nursing

Hey, I just took the psb for practical nursing. I needed to do very well in order to be seriously considered. I made decent scores in all sections but judgement and comprehension in practical nursing. I scored 43rd percentile which was very surprising to me. I have experience in the medical field and I know how to answer these types of questions. I met with a school tutor who specializes in this test and also answered them how she told me to. As if I was in charge and making decisions.. anyways, I really felt that I answered these questions correctly. I even looked up multiple study guides and templates in this section that had the SAME EXACT questions and I answered them correctly according to the answer key. I just don't understand. Has anyone else experienced this? Is there any explanation? This is what will keep me from getting into the program. Any insight is helpful! Thanks!
