"حصص" (Hissas) refers to the concept of "lessons" or "classes" in Arabic. It is commonly used in educational contexts to describe the structured periods during which students learn specific subjects, such as mathematics, science, or language arts. Each حصص typically has a set duration and is led by a teacher who guides students through the material. In many educational systems, حصص are organized into a timetable, allowing students to attend different classes throughout the day. This structure helps ensure that students receive a well-rounded education, covering various topics and skills necessary for their academic development.
