NCE EXAM ANXIETY HELP!!

Hey guys, I am currently now studying for my NCE exam. I am in my internship of clinical mental health Counseling graduate program and only have three weeks to study for the exam. I am so anxious. The only thing I’ve been using is the Pocket Prep and listening to audios from Spotify on NCE exam. For some reason I feel like the Pocket Prep is too easy. And I’m just nervous at the questions are gonna be so much harder on the NCE and nothing like the Pocket Prep. The purple book drains me and intimidates me. Let me know what I should do how to get started. I am so bad at taking tests. I get really bad Anxiety.
