ExploreAbout this exam
CM1 is one of the early subjects in the Institute of Actuaries of India (IAI) actuarial examination series, and the IAI's own site describes the Institute as "a statutory body established under The Actuaries Act 2006 (35 of 2006) for regulation of profession of Actuaries in India." The exam is split evenly between two halves: Actuarial Mathematics and Statistics. The mathematics half builds the core life-contingent toolkit - survival models, life tables, assurance and annuity functions, premiums, reserves and multiple-decrement ideas. The statistics half covers probability distributions, sampling, estimation theory, hypothesis testing, regression and correlation, and the foundations of risk modelling. CM1 suits candidates who have completed the earlier foundation subjects and are comfortable with calculus, probability and algebra; it is normally attempted alongside or just before CM2. Preparation works best in three phases: work through the IAI syllabus and study material so no learning objective is unseen, drill past question papers and solutions under timed conditions, and finish with a mock exam, which IAI publishes for the November session. Candidates should confirm exam structure, dates, fees and centres on the IAI website rather than relying on second-hand summaries, because IAI updates these details and this page does not reproduce them.
What you'll study
About IAI CM1 preparation
What does CM1 actually cover?
Two halves of roughly equal weight. Actuarial Mathematics covers survival models, life tables, assurance and annuity functions, net premiums, reserves and multiple-decrement models. Statistics covers probability, distributions, sampling, estimation, hypothesis testing, regression and correlation. Check the current IAI syllabus document for the definitive learning objectives before you plan study.
How is CM1 structured and how long is it?
The IAI publishes exam structure, duration and rules in its actuarial examination section. Those specifics are not reproduced here because the source page does not state them. Download the current syllabus and exam policies from actuariesindia.org, and treat any duration or mark figure from a forum or older note as unverified until you confirm it.
How hard is CM1 compared with earlier subjects?
It is a step up. The mathematics half rewards fluency with life-table algebra and annuity notation rather than memorisation, and the statistics half demands genuine understanding of estimators and tests. Candidates who only read notes usually stall; those who work problems daily and review errors tend to clear it. Budget several months of steady effort.
Can I retake CM1 if I fail?
Retakes are generally possible in a later exam session, but the exact policy on attempts, fees and any restrictions sits in IAI's exam policies and guidelines. Read that document directly rather than assuming, and plan your next attempt date from the published examination dates so you have a realistic study window.
Which half should I study first?
Start with Actuarial Mathematics, because its notation and life-table conventions recur throughout later subjects and take time to become automatic. Run Statistics in parallel at lower intensity, then increase it once the mathematics core is solid. Avoid leaving all of Statistics to the final weeks; hypothesis testing and regression need repeated practice.
Where do I find past papers and solutions?
IAI publishes question papers and solutions, plus results and exam announcements, in the actuarial examination section of actuariesindia.org. Work recent papers under timed conditions, then mark honestly against the official solutions. IAI also announces mock exams, such as those listed for the November 2026 session, which are useful final rehearsals.
What are the most common ways candidates fail?
Three patterns dominate: memorising formulas without being able to apply them to unfamiliar wording; skipping Statistics because it feels less familiar; and never practising under time pressure. A fourth is ignoring small errors in life-table arithmetic, which cascade through a multi-part question. Track your mistakes in a log and revisit them weekly.
What study material does IAI provide?
IAI lists study material with a published price list, including softcopy material, alongside its course education curriculum. Use the official material as your spine so nothing in the syllabus is missed, and supplement with your own worked summaries. Confirm current availability and prices on the IAI site, since these are updated periodically.
Does passing CM1 make me an actuary?
No. CM1 is one subject within a multi-stage examination series, and further subjects plus professional requirements follow. The IAI regulates the profession in India under the Actuaries Act 2006. Check the IAI's membership and credentials pages for the full pathway from student member through to Associate and Fellow.
