Not happy that I only scored an 85, but only needed 70 to pass. Now can legally use my drone in our roofing business and/or for hire.
Having a Private Pilots license both helped and created obstacles.

The internet drone course I took sucked! Fully 25% of the test questions were on subjects they never even broached. This after scoring 92%+ on their practice exams. After the first 10 of 60 questions I began to wonder if I'd pass, and I never take a test unless I'm pretty darn sure I'll pass.
Without my prior pilot schooling there is no way the course would have allowed me to pass.
No sense wasting extra intelligence. 70 would do and that is all it takes.
