WELCOME TO THIS GREAT EDUCATIONAL BLOG

Welcome to my Pre-Nursing Exam Prep blog. I hope it will help you prepare very well for the Pre-NLN entrance exam, popularly known as the PAX exam. This is one of the entrance exams required by some schools for those who want to pursue careers in the nursing field in the USA. I will attempt to break down the review materials into manageable parts so that you can systematically and efficiently prepare for the test with less stress. I will guide you to prepare for the entire content of the test. Hopefully, you will be able to pass after going through these series.


BEST OF LUCK!
