Lemme write the answer… 😛

Many distractions present to keep kids from studying, poverty in many urban communities forces parents to work long hours and not be as active of parents in their childrens’ lives, urban schools funded by low property taxes do not have the money to keep the best/most experienced teachers leading to revolving door of n00bie teachers, “typical” attitudes of students in urban environments discourage studying in favor of social/other activities.
