FCC GROL GMDSS Prep covers multiple FCC licenses including MP, PG/GROL, DO, RG, DM, DB, and T. It also offers the Ship Radar Endorsement as an add-on. Users can select to study only the elements required for their specific target license.
Each of the 2,860 official questions comes with a plain-English explanation that details why the correct answer is right and why the other options are incorrect. This approach helps candidates understand the reasoning behind the answers, not just memorize them.
No, FCC GROL GMDSS Prep is completely ad-free. The app explicitly states 'No ads, no in-app purchases, no subscription — everything is included' for a distraction-free study experience.
The mock exam feature accurately reproduces the FCC's scoring structure, where each required element is scored separately. You pass the mock exam only when you achieve passing marks in all necessary elements, mirroring the real testing center experience.
Memory tips are short hooks, acronyms, or number patterns provided with each question's answer. These are designed to help users associate the correct answer with familiar concepts, moving beyond rote memorization of isolated facts.
No account is required to use FCC GROL GMDSS Prep. The app emphasizes a no-sign-up, no-login, and no-email policy, ensuring user privacy and immediate access to study materials.
The app uses the official FCC public domain question pools for Elements 1, 3, 6, 7, 7R, 8, and 9, current for 2026. All questions retain their original wording and official answer keys.
FCC GROL GMDSS Prep offers several study modes including sequential study (resumes where you left off), random study (shuffled questions), mock exams, and a mistake review mode that saves incorrect answers until they are answered correctly.
