Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Element 8 is now complete.
The 20 Ship Radar Endorsement questions that depend on a diagram now ship with
their radar figures, taken from the official FCC pool document. Element 8 goes
from 280 to the full 300 questions, and the app now carries all 2,244 questions
and 2,244 flashcards across Elements 1, 3, 7, 7R, 8 and 9.
Every element now matches the official FCC pool exactly. A pool-completeness
check runs on every build to keep it that way.
Also in this update:
- Mock exams draw from the new questions automatically, including the figure
questions, so a Ship Radar mock is now a full-pool draw.
- Corrected the question and flashcard counts shown in the store listing, which
still quoted the pre-update figure.
