Which Bachelor's degree can I pursue, if I want to pursue actuarial science further?

Dear Abhimanyu , If you have planning for Acturial field than you should think of Maths hons, Economics or Stats Hons because that will help you to build your base in maths or economics though that's play important role in further Acturial Study. All the Best.

Actuarial science is coming up well and it is recommended to have mathematics but there is no imposed criteria. You may check about courses here http://www.actuariesindia.org/subMenu.aspx?id=226&val=ACET_FAQs&AspxAutoDetectCookieSupport=1
