Hello dear, Many many thanks to ERPPREP.COM that I got 90+ score in SAP MM certification. You guys believe or not but its true. I was so frustrated that number of times I have mailed to support @erpprep com and said that are you sure I will clear the exam.thank you so much for support. I also recommended to my colleague of MM and SD. Out of 80 questions i corrected more than 70. one wrong from master data.
