Hi there rida! Niteowl here to leave a quick review.
I like the first stanza and how it sets up a rhythm, though I think the line about continued desperate pleas is a little awkward. Maybe something like "perpetual pleas"? It looks shorter but seems to fit in terms of syllables.
I also like the overall idea of how school is terrible and how adults don't seem to get it. I know when I was in school, my mom would say things like "you're young, you don't have stress", which seems awfully ridiculous while I'm buried to the gills in classwork because every teacher thinks an hour of homework is reasonable.
However, I feel like I'm not really getting a sense of how school is. It tells us school is stressful and prison-like, but I don't really feel it. There's so many angles you could take here-the draconian physical structure of school (eg having to ask permission to go to the bathroom, the need to teleport across the school in order to get to your next class, rules about when you can eat/drink), the social stress (getting along with classmates, figuring out where to sit at lunch, cliques and bullying), the unrealistic homework expectations, the constant question of "when will I need to know this?", and probably more reasons I can't think of right now. You touch on some of this, but I really think you could play this up with more imagery and examples.
I'm also not sure what "winning" and "showing our might" looks like. Are these kids striking from school? Or is "winning" in this case just getting good grades and making it to graduation.
Overall, this isn't a bad start, but it'd be interesting to build upon this. Keep writing!
