These two books were my lifeline while applying to PA School. Maybe they can help you out! Each book was beneficial for different reasons.
1) So You Want to Be a Physician Assistant by Beth Grivett
The first one features several “a day in the life…” entries from different practicing PA’s in different specialities. It helps you understand what a PA does or can do and how much variety exists between specialties. I think it would be helpful to those of you who aren’t sure if you want to be a physician assistant just yet. This is a book that you can read in one sitting.
2) An Applicant’s Guide to Physician Assistant School and Practice by Erin Sherer
This is your practical step-by-step/how-to book about applying to PA School. What to do beforehand, during the application process, afterward and for the interview. Very useful!
