4. What is the difference between a Scholarship and a
Loan?

To put it simply, a scholarship is when a college or uni will pay for you to come to their school. Meanwhile a loan is the money you borrow for something, which will make you in-debt

When you take out a loan you have to pay it back, with scholarships you do not have to pay the money back it is yours to keep
