Passed this past Wednesday, yaya! Congrats to all you other 107 Pilots!
I used the Remote Pilot 101 course and highly recommend it. They definitely cover just about everything on the exam.
Many folks say the exam is super focused on: METARs, TAFs Sectionals and Airspace, and it seems it often is but one tip I can throw in is that you never know what you're going to get on test day so know it all. Many folks say they got tons of sectionals, others tons of weather & METARs/TAFs, etc. Mine was actually quite light on sectionals, charts and graphs, only two questions on METARs/TAFs, and when map/airspace q's came up they were always on the super crowded hard to figure out trick question ones
. Not a pilot before 107 so personally still working on understanding all the nuances of them.
My test had a lot on philosophy and regulations, things like hazardous attitudes, crew resource management, maintenance, Remote PIC roles & responsibilities, alcohol/drugs/impairment, etc. Fortunately for me knowing how to navigate trick q's and process of elimination those are the easier side for me so I was grateful for that.
Something I found super annoying was the grouping of exam questions like 4-5 in a row on the same topic, which made the experience like a roller coaster - one chunk of time I was like yeah I'm rocking this answering obvious q's in like 5 seconds going through 5 in one minute, other times I was hella stumped and took a few minutes per q for a while and was all freakin' out. Pretty sure they do this as the mind f trick you up part of the testing process to see how you perform under pressure. If you take the electronic test you can flag ones you aren't sure about to come back to them so I suggest making your best guess, then coming back to them at the end so you don't psyche yourself out and waste time.
Oh yeah the FAA loves trick questions, be conscious of exactly what info is pertinent to the question i.e. they may mention clear day or rain, but weather has no impact on the situation they're testing about, stuff like that.
I really didn't hard study anything else besides the Remote Pilot 101 course, combined with general knowledge I pick up from life, experience, the forums, reading, etc. - my suggestion is to do it a few hours each day for a week in that course, take the RP101 practice test once or twice until you have a decent score and go for it! the $99 is worth the investment since it's all in one place and you really don't need to master anything else to pass. Remember all you need is 70% to pass and most of your Remote Pilot airman knowledge is going to come from the real world and experience over time. Good luck everyone!
