Retirement tax questions

Just to double-check, as I plan to debit my Roth IRA account to pay for graduate school fees (and therefore avoid taking additional loans).

 

I have not held my Roth IRA for more than 5 years, and am currently 28 years old. If I debit my Roth IRA account to pay for graduate school fees, do I have to pay the 10% withdrawal? In addition, does my distribution get taxed as regular income?

 

Thank you for your help.
