The term "Fourth Class" can refer to various contexts, but it is often associated with educational systems, particularly in countries like India. In this context, Fourth Class typically denotes the fourth grade of primary education, where students are usually around 9 to 10 years old. The curriculum often includes subjects such as mathematics, science, language arts, and social studies. In some countries, "Fourth Class" may also refer to a classification in military or civil service ranks. For example, in the Indian Railways, Fourth Class can indicate a lower tier of seating or accommodation, often more affordable but with fewer amenities compared to higher classes.
