Chin up - Feb should be your day. You already have street credibility for your study/testing effort - most do not attempt the test.
I passed the exam 20 years ago (it was tough then). I left the biz for over a decade and reentered a few years ago. My NRRPT cert had expired so retaking the test was the best way to recert. Passing NUF, CORE, and misc site rqmts was a challenge after the elapsed time, so I studied hard for the NRRPT - and accomplished a failing grade. Like you I learned how to focus for a retest - which was successful at the next testing date. Gollnick's "Basic Radiation Protection Technology" 5th ed and practice tests were prime resources that worked for me. Congats on qualifying to even take the exam.
