Thank you so much guys.

Dell EMC data scientist certification exam was a big milestone for me and I have achieved the same with the great help from this web's practice tool. The questions on the tool are very near to the the one I faced in the real exam. However, the more important is the valuable practice and know how then the questions I feel, I was full equipped as I was aware of the exam pattern and also ready with the tricky questions. 
Big thanks to the team
