    Hello everyone this is Durga from chrompet, I joined Credo Systemz for my data science training course in JAN month. I have nearly 4+ years of experience as a python developer and also having some work experience in handling data. So I like to do Data Science course, and one of my friend referred me Credo Systemz. I had attended demo session at first with the trainer, he gave a complete overview about the course which impressed me and make me to join for the course. The session went extremely well, can able to learn my real time scenarios because of the experience of the trainer. Data Science course fees also worth for this training. Now I am confident enough that I have all the skills required to be a Professional Data Scientist.
