Anyone taken the CSN exam recently — how current is the study material?

Getting ready for the Certified Sleep Neurologist (CSN) board exam. Most of the prep materials I'm finding are 3-4 years old and sleep medicine has moved pretty fast in that time — especially around CPAP adherence protocols and newer scoring rules for pediatric studies.
I'm using the ABSM study guide and Kryger's Principles and Practice of Sleep Medicine. Is the Kryger still the gold standard or has something better come out?
Also curious how much emphasis the exam puts on pediatric vs adult sleep disorders. My clinical practice is almost entirely adult so I'm nervous about the pediatric scoring questions.

The ICSD-3 criteria are heavily tested. Make sure you know the current diagnostic criteria cold, especially for the hypersomnia spectrum disorders — those questions are tricky and easy to mix up.

Took it last year. Kryger is still the main reference — the exam seems to follow it closely. Pediatric content was maybe 15-20% of what I saw, so don't ignore it but it's not the majority.

Practice questions from ABSM are the most representative of the actual exam format. The free ones online are often outdated or off-format. Worth paying for the official practice exam.
