Is it worth getting a huge loan to go back to school in London?

I have been given a fantastic opportunity to move to London and attend the famed School of Communication Arts.

I need to make a decision this week about whether I am going, right now it looks unlikely as the course fees are so expensive. I’m not too worried about the “the high cost of living” in London. If I can stay in Hilton on Park Lane for 50 pounds, surely rent is going to be cheaper than here in Surry Hills. What worries me is that I already owe $25,000 for my bachelors degree and I will need to borrow that much again to pay the fees for the school.

Is a few years of this worth that much money:

Probably. But how am I ever going to pay that off? Useful advice come hither!
