Student loans are funds borrowed by students to help pay for their education, including tuition, books, and living expenses. These loans can come from the federal government or private lenders, and they typically need to be repaid with interest after the student graduates or leaves school. There are different types of student loans, such as subsidized and unsubsidized loans. Subsidized loans do not accrue interest while the student is in school, while unsubsidized loans do. It's important for students to understand the terms and conditions of their loans to manage their future repayments effectively.
