HOW TO PRACTICE ON SAP (IDES) FICO INDIVIDUALLY

Hi SAP Gurus,

I passed the certification exam during May 2007. Since then, I am trying hard to continue practice on FICO but am unable to find any sort of product to start practice on SAP IDES.

Can someone tell me if this could be purchased (licensed one) from anywhere?

Does SAP provides this facility?

Whom should I contact to get this?

Regards
