“pay attention to all your classes, it all becomes useful one day”

Easier said than done. It’s nearly impossible to keep focus on something for 5 hours straight, even if you care about it. Expecting young people to remember all the stuff that’s being forcibly taught to them and will definitely be useless for the huge majority of their life is ridiculous.

For anyone who doesn’t work in very specific fields, remembering what a couplet is has the same usefulness as a random trivia. At that point it would be more useful to tell students to go on a wikipedia rabbit hole of their choice for an hour, at least if they chose it themselves there’s a higher chance they’re interested and it’ll stick to them.

Also echoing what the other commenter said, the fact that there’s a single stressed person on a schedule trying to teach the same thing simultaneously to 30 different people with 30 different needs definitely does NOT help.
