I wouldn’t call anything we do here “training.” Ground consists of CBTs where Microsoft Sam reads the airplanes manual to you, reading powerpoints out loud in class and practicing (not learning) things in the sim/procedure trainer. Maybe they train you a little if you’re weak on stuff? I would say it compared unfavorably to most of my part 61 training, but the checking events were also much easier than my part 61 rides.
I have never struggled with aviation related training but showing up to the procedure trainer and having only memorized the flows as they are presented in the manual was embarrassing. Totally inadequate. Learned to run the jet from YouTube.
