 I have done my engineering from YCC in Nagpur and I am now an IIT Madras BSc student on the degree program. Actually I had taken 6 courses till now, calculus was there, laps transform was there, engineering mathematics was there and then I had probably can statistics then I had a Japanese course also. I started this BSc degree and then I came to know that NPTEL is also offering this mathematics courses also at least actually I knew that NPTEL offers engineering streams courses, but I had not explored this mathematics stream also because these courses give you a very good insight on what mathematics engineering does not have that much mathematical subjects. I wanted to explore maths more and more because I like this mathematical field very much and data science is full of mathematics so you have to develop it a lot. Courses that they can choose is the data structures and algorithms from Madhavan Mukun Sir that is there, it is a fantastic course then they can use discrete mathematics it is also very much used and you can explore these things so that it gets a very firm foundation on mathematics. It is very much important for data science even in tools basically the statistics courses, the probability courses that will actually help them in understanding the concepts.
