Our family is similar to what you said. My son is now a senior one. We are usually busy and seldom at home. When he was in junior high school, he often failed in math. Later, introduced by colleagues, the children were sent to excellent education. The teachers there are very responsible and know about our family. He usually cares about his study and life and often communicates with us. It's almost a semester now, and it's better than before, so I can pass it.
