Our schools need a complete overhaul, plus we are years behind in mathematics compared to other countries. Regarding the tariffs, best to do as little public kicking and screaming as possible and just find other markets. Some low fanfare tit-for-tat would be good too, start using the new foreign relations bill. Overall we will be fine, just signed Asian trade deal and India coming up plus UK after Brexit. Only iron ore will be a problem because next to impossible to find consumer equal to China in that regard.
