The secondary education teaches the kids what we gave em those foundation languages for, the alphabet and numbers .. it teaches em the advanced manipulation of those languages .. the advanced ways we manipulate them to do the more complex things in our lives.

Like say in primary school you were taught to write, nd then how to write a sentence. In secondary they then build on those two to teach you how to use complex blocks of sentences to achieve an aim for example a letter or a story or a poem or a report.. Its about advanced ways to manipulate those languages (alphabets and numbers) to do many of the things in our lives.

Then it also teaches em about the system theyre in (the planet earth) nd the laws that guide the behavior of the system they're in (physics, chemistry, biology, geography)

And also General knowledge... it aims to stack up a mini library of information up there that you can count on to navigate your world.

(These purposes are also crucial and dont need to be disrupted, they might need additions but not much disruption)
