Hello Brij

In almost all Branch you will have to Study Maths for 1 year. If you opt Mechanical, electrical or Civil then you will have to study 6 Maths Papers which includes Operatonal Research.

If you are asking about the specific branch which includes only maths then you will have to do Bsc.

I hope my answer will help you out.

Good luck
