I have no words to explain the joy and happiness. I so so happy, Yes, I have achieved it. I have got it, I am a Tableau Certified Desktop Specialist. I got my certification done today. 
Very very happy with the question tests this web has. The technique is unique and very helpful. I was able to improve a lot and this all I did in just 1 week.
