Izar, I’m not completely following what you are saying. I’m assuming you want to take the exams. Have you gone through the FAQ, it might answer your question. Furthermore, the link that Marek has given you contains links to PDFs where is outlined what topics are relevant for the exams and what materials are available for preparation. This link www.sap.com/services/education/catalog/businessobjectstraining/businessintelligence/curriculum.epx?context=[[BOBJ_BI_WI_XI30]]| might be useful as well (a link from the FAQ by the way). You’ll have to copy and paste it, as the links messes up due to the characters used.
