The Best Case
Some gifted children just arrange with life as it is and get good grades in spite of being bored. They make the best of their situation and normally are among the best students in each of their classes. They often try to satisfy their thirst for knowledge outside school to compensate for their boring lessons. Others start helping their classmates and thus take on the role of a second teacher.
The Most Common Case
Most gifted children get easily bored in classes and stop paying attention when lessons are just too boring for them. Instead, they start doing their homework, they write notes with their classmates, they draw little pictures in their notebooks or they stare out of the window while their mind wanders. These children still get acceptable and sometimes even outstanding grades but they could do better.
The Worst Case
There are some gifted children who get so bored that they start interrupting the lessons. Others refuse cooperation with the teachers or classmates. The result is often enough that these children are thought of as lazy, difficult or stupid. Many of these gifted children leave school with very poor grades or even without a high school diploma at all although they could have gotten outstanding grades with the right encouragement.
