Amazing!!! Just one word to describe

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 gave C1000-162 and received result history and my performance. I could analyse how well did i fare in IBM Security QRadar SIEM V7.5 Analysis mock tests and strategize further attempts. This is good, actually.
