**Why Master Data Science I ?**

Master Data Science will give you an edge over others who are of similar work experience. This course we recommend if your experience is less than 5 years in the industry.

You will be doing multiple projects as part of this course and each course will cover from basics going to advanced preparation.

You can even decide to master 2 streams later on out of the 5 streams – Big data , predictive modelling , machine learning, time series forecasting , NLP.

While other institutes show you all these courses as separate, we recommend you to study all the things which we have listed together to become an all round data science professional

The more knowledge you carry , the better you would be looked at.

Your CV would have higher chances of getting shortlisted compared to others since you would be knowing way more than them.

Also it would help you progress up in the corporate ladder due to the knowledge that you would carry
