With the new drone laws, you’ll only have to take a free online training in two years. No more going somewhere and paying for the recurrent test. Pilot Institute and probably the other 107 courses mentioned in this thread will teach you about that.I passed with a 90% with self-study, tests online, FAA study guide etc. But am interested in how I can maintain/grow knowledge, stay abreast of changes, updates, interpretations, etc. and score better on the next test in two years. I may join the pilot institute next year (off year for testing) to accomplish those items.
