Yes, this is definitely homework. :) So here are some questions for you:
- In your country, is university education free? Do you think this is a good idea? What do you think would happen if the situation were otherwise?
- Think of two positive points and two negative points about free university education.
- Think of two positive points and two negative points about having to pay for your university education.
- Are there any solutions to the negative points you've written down?
That should give you plenty of ideas to use when writing. You can always reject anything that isn't necessary.
