A school class is a group of students who come together to learn about a specific subject or topic. Classes are usually led by a teacher, who guides discussions, provides instruction, and assigns homework. Common subjects include math, science, history, and language arts. Classes can vary in size, ranging from a few students to over thirty, depending on the school and grade level. Classes typically take place in a designated classroom, equipped with desks, chairs, and learning materials like books and computers. Students participate in various activities, such as lectures, group work, and hands-on projects, to enhance their understanding of the subject matter.
