SAP Ariba Sourcing ERPPrep - Passed Exam 6 days after purchase

I have been a member of ERPPrep a little over two weeks and have used the exams extensively. It took me 6 days from the day of purchase to taking the exam to pass the Ariba Sourcing certification. I highly recommend the ERPPrep exam prep! I am on the Ariba Integration next. Just too bad that ERPPrep does not offer Ariba Contracts.
