How much of what we learned at school actually turned out to be true — or useful? This week, we’ll revisit the facts, rules and life lessons we grew up with, question some classic “you’ll need this one day” moments, and talk about what school got right, what it got completely wrong, and what nobody bothered to teach us at all. Open to all levels. Cash only. Please reserve your spot at lettersandnumbers.am. For questions, contact @lan_yerevan or @sophie.zedguenisova.
