Italy: my 15yo kid has such atrocious writing, I'm embarrassed to even call it chicken scrawl. How the teachers decode eg any of 47 ways of scratching the letter 'a', or indeed any others, i have no idea. I've been complaining about it since the kid was 5, and just silently seething for the last 5 years. Other battles to fight.
