Do not sit for exam without giving online mock test

hii
I am a professional and have more than 6 years of experience. I thought of giving IBM C2010-653. I had become overconfident of my knowledge. But, my colleagues asked me to take a demo test on this site. The test gave me the real picture and i immediately enrolled for the package. With personalized results after test, i came to know about my understanding of the syllabus. I would suggest every aspirant to first give simulated test here and then give actual test.
