crowded classroom from the perspective of someone in the back

crowded classroom from the perspective of someone in the back. People are mostly standing, and they seem to be facing the front where a young woman is standing in front of a green chalkboard. Most of the people in the room have dark hair and dark skin. The room appears old and is sparsely furnished. A black and white pole runs from the floor to the ceiling. There is writing on the chalkboard behind the young woman. Most of the students have a notebook or paper in their hands. There is a loud noise in the background.
