DTC has rebuilt its Part 107 preparation course from the ground up, cutting the average study time from five weeks to two. The previous version of the course covered every topic in the FAA's testing supplement at equal depth, regardless of how often that topic actually appeared on the exam. The new version doesn't.
The rebuild started with three years of anonymized exam-attempt data from DTC students: which questions people got wrong, which topics correlated with a failed attempt, and which sections students skipped entirely because they felt confident already. That data reshaped the syllabus around what the exam actually tests, rather than around the supplement's table of contents.
A shorter course, not a lighter one
Airspace classification, weather, and loading/performance now get roughly 40% more instructional time than in the old course, because those three topics accounted for the majority of failed first attempts. Regulatory history and radio communication, which rarely appear on the exam in more than one or two questions, were trimmed to a single review module each instead of a full unit.
The pass rate on the first exam attempt held steady at 89%, the same as the previous course version, despite the shorter study time. Internally, that was the number the team was watching most closely — a faster course that also lowered pass rates wouldn't have shipped.
How the new question bank works
The course now includes over 800 practice questions, up from 350, pulled into adaptive quizzes that weight toward whatever topic a student is currently missing most. A student who's consistently getting airspace questions wrong will see more airspace questions until that stops being true, rather than working through a fixed, linear question set in course order.
Availability
The updated course is live for all new enrollments now. Students already partway through the old course version can switch to the new syllabus from their dashboard at no extra cost, though DTC recommends finishing whichever version you've already started rather than switching mid-course.
