I dont remember my security awnsers. Is there a way to change the questions?

Click here for information. If you can't reset them through the method described in that article or by sending yourself a rescue email(the email may take a few hours to arrive), contact the iTunes Store staff via the link in the 'Additional Information' section.

It isn't possible to create a rescue email address without correctly answering two of the questions. Nobody on these boards can reset them for you.
