What do you mean by gifted? QI? Or just kids with better results at the exams? In Germany, some schools, start to do the separation when kids have only 10 year

What do you mean by gifted? QI? Or just kids with better results at the exams? In Germany, some schools, start to do the separation when kids have only 10 years old. It seems to me too much stress and it's not even effective, bc you do it having an exam in consideration. School is not everything, look at Einstein :)
