I have recently completed SAP HR training from a certified training institute. However I have not yet appeared for the exams and I want to practice the exercises for a better understanding. Is it possible to download the software in my laptop? If yes, then kindly let me know how do Ido it & if there is any prerequisites to be fulfilled? I have a broadband connection of 256kbps, hard disk space 80GB, 512 MB RAM with windows XP SP2.
