How many weeks did you study for the CBT exam and what resources helped most?
I'm an audio engineer with 6 years of field experience planning to sit for the CBT — Certified Broadcast Technician exam this fall. I've worked mostly on the production side so I'm weak on RF transmission and FCC regulation sections. Started studying 5 weeks ago at about 45 minutes a day on weekdays.
My practice scores average around 67% right now and I want at least 80% before I book the real exam. Electronics fundamentals are fine — Ohm's law, impedance matching, I know that cold. It's the regulatory compliance questions that are destroying my score.
I've been using the SBE study guide and some YouTube playlists but they're not deep enough on FCC Part 73 material. Has anyone used a resource that covers regulatory content in exam-relevant detail without just reproducing the CFR verbatim?
Also curious how the actual exam felt for time. I've heard it's 100 questions and the limit isn't that tight, but I tend to second-guess myself and run long on timed tests.
I passed first attempt with 82% after 8 weeks at about an hour a day. The RF propagation and antenna theory questions were harder than I expected — the SBE guide undersells how much math shows up for that topic specifically.
The SBE guide is fine for concepts but you really need to read FCC Part 73 and Part 74 subparts directly. It's dry but probably 20% of the exam comes straight from those rules. I flagged every wrong practice answer and traced it back to a specific CFR section.
6 years of production experience should carry you through 60% of the exam. The regulatory section is what separates people who pass from people who don't. I'd put at least 40% of your remaining study time there.
100 questions, 3 hours. I finished in about 90 minutes and had time to review everything twice. You're not going to run out of time unless you completely freeze on something.
