Bueno site for sap preparation

I am from Galicia. I find the site erpprep.com superb, excellent. I tried the site for the preparation of sap modeling and data management with sap Business Intelligence with BW and BI certification exam. I am very happy with the result. The site helped me through the ups and downs and the nervousness of the journey of sap preparation. I like the site. It is very helpful. C_TBI30_74 Certification Questions on the site very very good too.
