What is CM1? Complete CM1 Actuarial Mathematics for Modelling Guide (Syllabus, Format, Tips)

Introduction to CM1 – Actuarial Mathematics for Modelling

CM1 (Actuarial Mathematics for Modelling) is often the first major hurdle for actuarial aspirants. It lays the foundation for financial modelling, interest theory, life insurance mathematics, and reserving techniques. It’s not just about passing a paper — it’s about building the mathematical mindset of an actuary.

CM1 Structure: Two-Part Assessment

CM1 consists of two mandatory papers:

Paper A – Theory & Conceptual Understanding

• Mode: Word-based descriptive answers
• Duration: 3 hours 20 minutes
• Weight: 100 marks
• Focus: Core concepts in interest theory, life insurance mathematics, reserving, and profit testing

Paper B – Excel-Based Practical Application

• Mode: Excel spreadsheet-based questions
• Duration: 1 hour 50 minutes
• Weight: 100 marks
• Focus: Practical application of CM1 models and calculations using Excel

Note: You must appear for both Paper A and Paper B in the same exam session.
