ExploreAbout this exam
CS1 (Actuarial Statistics 1) is a subject within the Institute and Faculty of Actuaries (IFoA) curriculum - the professional body whose Qualify section covers becoming an actuary, the curriculum, and exams. CS1 sits in the statistics strand of the actuarial qualification, building the probability and statistical foundations that later subjects and practice-area work depend on. It is aimed at candidates working toward IFoA qualification - typically graduates or career-changers with a strong mathematical background - who need rigorous, examinable competence in probabilistic modelling and statistical inference rather than surface familiarity. Because the IFoA's public pages for this subject and its exam regulations are currently archived, we cannot state the current syllabus wording, exam format, duration, pass mark, fees, or retake rules from the source; those fields are marked for review rather than guessed. Preparation should therefore start from the official curriculum and exam pages on actuaries.org.uk, plus the IFoA Virtual Learning Environment, which the source describes as offering thousands of learning resources, short courses, microlearning materials, event recordings and research outputs. Archived pages can be requested by emailing [email protected] with the page title and original URL. Treat any figure you see elsewhere - including older study guides - as unverified until confirmed against the live IFoA pages.
What you'll study
About IFoA CS1 preparation
What is CS1 and where does it fit in the IFoA qualification?
CS1 is Subject CS1, Actuarial Statistics 1, part of the IFoA curriculum listed under the Qualify section of actuaries.org.uk. It covers actuarial statistics at foundation level. The source pages we hold are archived, so we cannot confirm its position relative to specific later subjects; check the current curriculum page.
What is the exam format and how long is it?
We cannot state this from the source. The IFoA subject and exam-regulations pages we retrieved are archived placeholder pages that contain no format, duration, or question-count information. Confirm the current format on the live IFoA curriculum and exams pages before planning your exam-day timing.
What is the pass mark and what does the exam cost?
Not stated in the available source, so we do not publish a figure. Pass marks and fees are set by the IFoA and change between sessions; older study material frequently quotes outdated numbers. Check the current IFoA exam pages or your member portal for authoritative values.
How hard is CS1 compared with other subjects?
Difficulty is not something the source quantifies, and pass rates are not published there. Anecdotally, statistics subjects reward sustained practice over last-minute memorisation, because exam questions test applying distributions and inference rather than reciting definitions. Build in time for worked problems under timed conditions.
Can I retake the exam, and how many attempts are allowed?
The source does not state retake rules, attempt limits, or sitting restrictions, so we mark this for review. The IFoA exam regulations page is the authoritative reference; it is currently archived, so request it via [email protected] with the page title and original URL.
How should I order my study across the statistics subjects?
The source does not publish a prescribed sequence, so treat any ordering advice as guidance rather than rule. Sensibly, secure CS1's probability and inference foundations before subjects that assume them. Confirm the official structure on the current curriculum page, then map your own plan against exam sittings.
What official learning resources exist?
The IFoA Virtual Learning Environment is described in the source as offering access to thousands of high-quality learning resources, short courses, microlearning materials, event recordings, research papers and working party outputs across every stage of the actuarial journey. Members can also log in and browse the member portal for further material.
Why do some IFoA pages show as archived, and what can I do?
The source explains that older pages have been archived as part of ongoing updates to digital content and performance. You can visit the homepage, use the VLE, or email [email protected] with the webpage title and original URL; the IFoA aims to respond to archive enquiries within 5 working days.
What are common failure modes for candidates?
The source gives no failure statistics, so this is general guidance: weak grasp of distributional relationships, skipping derivation practice, poor time allocation in long calculation questions, and relying on outdated syllabus summaries found online. Verify every syllabus detail against current IFoA material before relying on it.
