Coming from a computer engineers' background, yes it was indeed tough as passing % for SAP Basis module is 63%
You flunk and your 34k exam fee goes in vain and you don't get dumps like in case of CCNA,OCA,RHEL certification exams
Had to complete 6 books each of 400-600 pages covering SAP installation,administration,etc.
A lady sitting behind me for SAP HR flunked and I could only score 64% giving me a heartbreak.
