SAP BW4H Success with Erpprep

I have 4 years of experience in SAP. I have decided to write SAP BW4H certification exam however I was not prepared as per syllabus defined. I decided to take up ERPPREP.COM online practice exams and I like the way questions are formed fit for syllabus. I scored 88% in exam yesterday. I recommend SAP candidates to practice with this site to improve confidence and understanding of exam.
