I'm thinking I may have to reschedule my AAPC exam until after the holidays. I have been studying the 2018 books and I'm wondering if the 2019 exam will focus alot on the new changes for 2019. Will it be a big deal? Will the exam really be that different? Will it be so different that it may cause me to fail the exam? And if so, is there a way to prepare myself for the changes that might be on the exam?
