Inside a classroom in Tabu, Nigeria, approximately nine male students are seated at individual wooden desks with attached benches. They are uniformly dressed in light checkered short-sleeved shirts and dark trousers or vests. The visible left wall is a textured, light brown surface. Natural light illuminates the right side of the room from an unseen window, casting the left and foreground into shadow. Each student has multiple sheets of white paper on their desk and is actively writing with a pen or pencil. A light blue scientific calculator is positioned on a desk in the mid-foreground. The individuals exhibit concentrated focus on their respective tasks.
