I gave the demo test on erpprep.com. I was wondering whether i should subscribe for the practice tests. But, the site is very safe and secure. The payment mode is so safe that it actually made me feel great while giving the sap businessobjects business intelligence certification exam. I will certainly recommend this site to all those who are set to prepare for C_BOBIP_42 certification exam. The site will take you through everything that the actual exam involves. The subscription of the questions too is very reasonable and very helpful.
