ExploreAbout this exam
CS2 - Actuarial Mathematics is a Core Principles subject in the Institute and Faculty of Actuaries (IFoA) Curriculum 2025, as listed on the IFoA site under Qualify → Curriculum → Core Principles. It is aimed at candidates progressing through the IFoA qualification who need the mathematical and modelling foundations that underpin later specialist practice. The IFoA describes the Curriculum section as "All the information you need under our current curriculum," and the Exams section as "Key info for exams including dates and essential resources." This page is an independent study resource; it is not affiliated with, endorsed by, or produced by the IFoA.
Important limitation: the IFoA's CS2 curriculum page could not be read when this page was compiled - it returns only the notice "This page has been archived." The exam timetables page returns the same notice. As a result, the current CS2 syllabus breakdown, exam duration, number of items, pass mark, fees, sitting dates and booking deadlines are not confirmed here and are marked for review rather than guessed. Candidates should verify all of these directly before planning.
To prepare, start from the official CS2 syllabus and core reading held in the IFoA Virtual Learning Environment (VLE), which the IFoA describes as offering "access to thousands of high-quality learning resources, short courses, and microlearning materials." Build a study plan around past-paper practice under timed conditions, and check the exam timetable and booking deadlines early through your member portal.
What you'll study
About IFoA CS2 preparation
What is CS2 and where does it sit in the IFoA qualification?
CS2 - Actuarial Mathematics appears on the IFoA site as a Core Principles subject within Curriculum 2025, under the Qualify → Curriculum menu. The IFoA labels that section "All the information you need under our current curriculum." The detailed syllabus content for CS2 could not be read from the archived page, so confirm the current syllabus in the VLE before you start.
What is the exam format - how long, how many questions, multiple choice or written?
Not confirmed. The IFoA CS2 curriculum page returned only the notice "This page has been archived," so duration, item count and format could not be verified. Do not rely on figures from older sittings or third-party summaries. Check the current CS2 pages via your member portal or the VLE, or email [email protected] to request the archived page.
What is the pass mark, and what does it cost to sit?
Not confirmed from the source. The CS2 curriculum page and the exam timetables page both returned only the archived-page notice, so no pass mark, fee or booking deadline could be verified. Obtain these from the IFoA directly before budgeting. This page deliberately leaves them blank rather than quoting unverified numbers.
When are the CS2 sittings and when do bookings close?
Not confirmed. The IFoA exam timetables page displayed only "This page has been archived," so no sitting dates or booking deadlines could be read. The IFoA site does describe an Exams section as "Key info for exams including dates and essential resources" - start there, then confirm in your member portal, since deadlines are easy to miss.
Can I retake CS2, and how many attempts do I get?
Not confirmed from the source. The retrieved pages contain no retake policy, attempt limit or result-validity information. The IFoA site does point candidates to an "After exams" section covering "Mitigating circumstances, appeals, counselling, opportunities," which is the right place to look for what happens after a sitting. Confirm the current rules with the IFoA.
How hard is CS2 and how long should I study?
No difficulty rating or recommended study hours could be verified, because the CS2 page is archived. Treat any specific hour count you see elsewhere as unverified. A defensible approach is to work from the official syllabus and core reading, then test yourself with timed practice under exam conditions and iterate on weak areas until performance is consistent.
Where do I find the official syllabus and study materials?
The IFoA directs candidates to its Virtual Learning Environment (VLE), described as an online learning platform offering "access to thousands of high-quality learning resources, short courses, and microlearning materials to support every stage of your actuarial journey, including event recordings, research papers and working party outputs." Members can also log in and browse the member portal for curriculum and exam information.
How do I get an archived IFoA page, such as the CS2 curriculum page?
The IFoA says: "If you need help or would like to request access to an archived page, please email [email protected]." Include the title of the webpage or document and the original URL, and for conferences the name and year. The IFoA states: "We aim to respond to your archive enquiry within 5 working days."
What are the most common ways candidates lose marks on a paper like CS2?
Specific CS2 failure modes cannot be sourced here, so treat generic lists with caution. Reliable habits: read the whole paper before allocating time, show method and workings so partial credit is available, watch units and rounding, and practise full papers to time rather than reading solutions. Confirm the current exam regulations and any calculator or materials rules with the IFoA.
In what order should I take CS2 relative to other Core Principles subjects?
No recommended study order could be verified from the source, since the CS2 page is archived. The IFoA publishes its curriculum structure under Qualify → Curriculum, which is the authoritative place to check prerequisites and subject sequencing. Confirm current guidance with the IFoA rather than following advice written for an earlier curriculum.
