Actuarial Science – UK & Indian Exams (Up to CB1)

Introduction to Actuarial Science

Actuarial Science is a field that blends mathematics, statistics, finance, economics, and risk management to solve complex problems faced by insurance companies, banks, pension funds, and financial institutions. Actuaries are recognized as global risk professionals who analyze uncertainty and financial risk to support businesses and governments in making sound decisions.

The actuarial profession is governed by professional bodies such as the:

• Institute and Faculty of Actuaries (IFoA), UK

• Institute of Actuaries of India (IAI)

• Society of Actuaries (SOA), USA

• Casualty Actuarial Society (CAS), USA

In both the UK and Indian actuarial exam structures, the Core Principles stage forms the foundation. This includes subjects:

• CS1, CS2 (Actuarial Statistics)

• CM1, CM2 (Actuarial Mathematics)

• CB1, CB2 (Business subjects)

This write-up will cover all papers up to CB1 in full detail.
