Hello Vaishali,

Data Science is becoming a very popular field in recent times hence you have chosen a good course. This course is a mixture of computer science, mathematics and a lot of statistics. Hence doing BSc Maths would be really beneficial. You could take BSc Data science in regular mode too provided the college is a highly equipped and reputed one, otherwise you may end up getting poor training and placement. So it is good to do BSc Maths in regular and take data science course online from an ivy league school if possible or any other globally reputed institute, in India IIT is also providing online course on data science. See to it that you are able to manage both together as both need a lot of time and dedication to master. You will have a great career with this stream and further you may take up masters course in pure data science to become a data scientist. Choose an online course wisely after thorough research .

Also another option for you is to take undergraduate program in Math with specialization in data science but for that you may have to go for international universities for example UNIVERSITY OF BATH,UK offers a BSc Hons in Mathematics,Statistics and Data science for 3 years starting from September 2021. There are many other universities too outside India that you can checkout.
