Thanks to Erpprep, I got 75% in 1st attempt for SAP certification Exam . Just reading books or with all hands on practice too, To clear the SAP exam in 1st attempt will not be possible without ERPprep.
Even thought I have got 93% to 96% in Erpprep Mock test consecutively, But got only 75% in SAP exam.
Questions are 90% same as in Erpprep. But I know the answers are not 100% correct. So please do your own study and validation for the correct answers.
But overall I will recommend for every one who is preparing for any SAP exam for the ERPprep, If want to clear in 1st attempt.
