Student’s Testimonial

I attended the Data Science Course at Jagathi IT and it was a fantastic experience. The curriculum is structured to help students master the essential vocabulary in Python (and R). All-in-all I felt the program delivered exactly the skills that I was looking to build. I'd recommend it highly to anybody who wants an effective foundation in Data Science and wants to Upscale.

Jagathi exceeded my expectations in a way I had never even thought possible. I expected a single mentor from Jagathi, but I ended up getting several people who guided me throughout.

The course is structured in a way so that people who have a good grasp of the fundamentals of programming can better themselves in higher level topics, which are commonly asked in tech interviews.

The most beautiful aspect of this program is that you are able to apply the learnings to the real-life business analytics problems as well. There are various points that contribute to this, such as the quality content that is designed by the world-class faculties. The turnaround time for your queries is really low similar to a regular classroom program.

At work, it helped me create authority over the areas I used to be uncertain about earlier; which resulted in better insights and in-depth reporting.

An investment in knowledge pays the best interest. – Benjamin Franklin
