Dear Student,

Sorry to inform you , But unfortunately no.. after 1st year in Maths , you can't get direct admission in 2nd year for another subject .

To get admission in B.Sc Data Science , you need to start again by enrolling in 1st year with fresh admission .

Or , you can also go for Engineering field with CSE in data Science Specialization . In that curriculum , you will get Maths also in some parts of your semesters
