There are primarily three major streams after class Xth. Students can choose between Science, Commerce and Humanities/Arts. All of these three streams can be generally categorized based on the core subjects and the career fields they will land you to. For instance, the science stream is usually related to medical, engineering, pharma, and other such fields of study, while the Commerce stream relates to business, trade, commerce, and financial sector. However, the Humanities/Arts stream is the widest of all, covering a whole lot of study fields, including Languages, Political Science, Psychology, Sociology, and a lot more.
