I'm guessing from your writing that you are a foreign applicant. If that is the case I understand it can be very difficult to get loans in the US. Simply being admitted will not be sufficient and you are better off trying to obtain financing in your home country.
If I'm mistaken and just mis-reading your English and you are a US citizen then you have a plethora of options. You should qualify for roughly $20,000 in Federal Loans, you can get additional loans at higher rates from the government, private banks or even Sallie Mae. Most graduate student loans will allow you to take out a loan up to a maximum of the Student Budget the school gives you. So theoretically you could take out a ~$90k loan to cover all your expenses. Each loan will vary on when you get the money and the method/terms of repayment.
With QE3 well underway, I presume it would be easier and cheaper for us to get loans? Invest in GLD and take out a bunch of loans in USD. It may not be that hard to pay back when you are done.
