education system is designed for average children, if you're too smart or too dumb, you'll fail.
I suspect with smart children, they usually don't want to memorize boring bits, in first years they are used to understand everything necessary during the class and generally didn't have to spend any time preparing for the school at home. as time passes, school becomes more difficult and students are required just to memorize rather than actually understand. this is why many smart children are taken by surprise at some point, they are not used to memorize knowledge just to pass the tests and many times they would simply refuse to do this and therefore fail.
it makes sense perfectly. look at some smart and successful people on the planet, you will see the same pattern: in real world - success, academically failures.
