I wouldn’t start by buying a course.
Meta already puts out a ton of solid free stuff, and YouTube is packed with decent tutorials that cover the basics just fine. The real issue usually isn’t missing info—it’s people just sitting there watching more and more content without ever actually launching a campaign.
I’d get the fundamentals down first (objectives, audiences, pixel, creatives, tracking, the usual), then throw a small budget at it and start testing. Yeah you might lose a bit of money, but that hands-on experience is worth way more than another 20 hours of videos.
Can’t speak to that specific course though—I never bought it, so no idea if it’s worth the money. Hopefully someone who actually took it can chime in.
For me everything only started clicking once I stopped watching and just started doing.
