B.Sc Maths

Let me put down some of the verticals which people generally choose (as per popularity in descending order) :
Masters in Statistics or Mathematics or maybe some other one-year certification course in Statistics.
Actuarial Science (actuarial aspirants generally join actuarial society along with your graduation).
MBA
Corporate Job
Government jobs (Grade A)
Indian Statistical Services (ISS)
Defence services
Civil Services(rarely people go for civil services)
Government Jobs (Grade B)
SSC-CGL (Statistical officer)
RBI
Summing up all this, I must say people with fair knowledge of Statistics are in huge demand in the present scenario and this demand will remain there in upcoming few decades at least.
