Which is a sustainable practice?

Answer:
Dear Mary, don't be alarmed to see prices on college websites. You can pass the exam well and enter for free. And in the case of paid education, you can get financial assistance. Financial assistance can be in the form of:
-Grants;
-Loan for education;
-Student Loans;
-Maternity loans.
So do not worry and be sure to apply, education is more than affordable for you.
