I did that. Complete waste of time for me. I can get by in a few languages but Latin didn't help with any of those.
What (afaik) they don't do which would have been useful, is a bit of human psychology, a simplified CBT(Cognitive Behavioural Therapy) approach, similar to Mindfulness.
Kids (and too many adults) have their heads full of illogical ways fof thinking which only make sense to the person, to get some sort of subconscious gratification.
EG kids let themselves believe it's clever to slide out of school and hang around in the middle of town all day, whereas if it was explained to them how to go about it, they could get more pleasure from going to classes and getting good marks. They aren't taught what sort of thinking & doing patterns, actually help. Instead, they delude themselves and get a kick out of being a rebel.
I was really bad at self discipline, at structuring my time and managing it. Decades later I'm only a bit better - if I put my mind to it. If we were all taught from school year one, how to go about doing the things which need to be done, I'm certain it would make everyone's life better.
There's a highly recommendable book, "
Games people play" by Eric Berne(1964). It can be alarming. You read about a load of stereotypical behaviours which he calls "maladaptive" - or dumb, then you recognise yourself doing some of them.
Berne explains how a "game" works for the player, then you see the behaviour repeated over and over all around you.
Apart from Games, there are also Rituals, and there are Pastimes, each of which has a place. Berne added Procedures, though other writers split things differently.
