User: At 18, her education IS her own responsibility, just as she can now vote, rent property, buy property, marry etc. She is an adult. The government used to provide grants for adults to study in higher education, but they don't anymore. That doesn't make it the OP's financial responsibility.
The point I was trying to make was that the OP can't ask that "the government" (there we go again with the mystical money-making organsiation) treat her daughter like an adult for the purposes of not including her parents' income in the financial calculations, yet also expect "the government" to fund her entire university education with a loan that would "cover everything" because she can't afford to do it. She can't have it both ways.
If she wants "the government" to treat her 18 year old daughter as an adult (which she is), then said daughter needs to pay her own way through university. But she thinks "the government" should have to provide a loan that will "cover everything".
Since grants are no longer provided (and even when they were, they certainly didn't cover everything; many students also had to work), and everyone knows this, and the OP has four children, she really should have been making herself aware of how it works, but she seeems to have no clue.
