IBM Cognos Analytics Author V11 certification preparation tests

Tons and tons of resources were researched and analysed by my group of friends. But we did not find anything useful. Then someone gave me the link of this site. It has something that no other resources provided - personalization. I purchased practice exam for IBM C2090-621 and received result history and my performance. I could analyse how well did I at the subject mock tests and strategize further attempts. This is good, actually!!
