Study tips for ARRT Radiation Therapy board exam

I’m a new grad getting ready to take the ARRT radiation therapy boards, and I could really use some advice! My whole class has failed so far :( I’ve been using the new Mosby’s, Laura Nappi’s guide, Radiation Therapy Essentials, and the ARRT outline to study.

For those who’ve already taken it (or are prepping now), what helped you the most? Any practice exams, flashcards, or study tricks that made things click? I feel like physics/dosimetry, QA, and treatment planning are the hardest for me right now.

Also open to any online resources, study groups, or little hacks you wish you knew sooner. Appreciate any help! 🙏
