Final answer:
The federal government pays interest on subsidized student loans while students are enrolled in school at least part-time, but students are responsible for the interest on unsubsidized loans.
Step-by-step explanation:
The interest payments made by the federal government while students are enrolled in school at least part-time vary depending on the type of loan the student has. For subsidized federal student loans, the government pays the interest while the student is in school, during the grace period, and during deferment periods. However, for unsubsidized loans, the interest accrues and the student is responsible for paying it. It's important for students to understand the terms of their loans and how interest payments work to make informed decisions.
