Failed my first CBM attempt with a 71%, which stung since I'd been doing local TV weather for four years already. The problem wasn't the broadcast side — it was the science depth. The AMS really does expect you to explain mesoscale convective systems and synoptic patterns at a level most operational meteorologists don't use daily.
Second time around I spent 8 weeks studying, 90 minutes a day on the theory sections. I made flashcards for every conceptual topic in the AMS study guide and quizzed myself on thermodynamic diagrams until I could read a Skew-T in my sleep. That alone probably added 12 points to my score.
My final score was 84%, comfortably above the passing threshold. If you're coming in from a non-degreed background, budget at least 10 weeks. If you have a meteorology degree and solid broadcast experience, 5-6 weeks is probably fine. The broadcast ethics section is shorter than you'd think but don't skip it — those questions are easy points.
Anyone else find the radar interpretation questions harder than expected? I thought I'd breeze through those but the dual-pol stuff tripped me up on test one.
Four years of broadcast experience here and I barely passed at 75% on attempt one. The thermodynamics section is no joke. I'd recommend anyone without a met degree to really drill the chapter on stability indices before sitting.
The ethics section surprised me too — I expected it to be filler but some of the scenario questions were genuinely tricky. Spent maybe 4 hours total on it and those turned into reliable points on exam day. Don't skip it like I almost did.
The dual-pol questions got me too on my first run. I pulled up every NWS training module I could find on ZDR and correlation coefficient interpretation — those free resources actually helped more than any paid prep material I found. Ended up passing with an 80% on attempt two.
Congrats on the 84%! Quick question — did you use any specific practice tests or mostly just the AMS official materials? I'm about three weeks out from my exam date and feeling shaky on the upper-air analysis stuff.
