It did, thank you so much.

It's the shift from compulsory education to elective. You're now in school because you want to be, not because you have to be. The attitude of teachers changes a lot.

In my school, it also shifted from a school uniform to "business". It felt like an epic transformation.

It's all surprising to me. I did not know there were formals at that age. I thought they were a grad thing.
