Best CISI IISI Mock Exams & Study Materials 2026: How to Choose
Not all CISI IISI study options are equal. We compare the included official workbook, free PDFs, classroom courses, and online question banks so you can choose the right prep to beat the 53% pass rate.

With a pass rate of just 53% and a broad, calculation-heavy syllabus, choosing the right study materials for the CISI International Introduction to Securities & Investment (IISI) exam matters more than most candidates realise. The wrong approach wastes time and, worse, your exam fee if you fail.
This guide compares the main categories of IISI preparation so you can decide what actually fits the way this exam is tested.
🎯 What to look for in IISI prep
- Applied questions — across every asset class, not just definitions
- Full coverage — all 10 chapters, weighted like the real exam
- Worked calculations — step-by-step yields and NAV premiums/discounts
- Realistic simulations — 50 questions, timed, at the 70% pass mark
- Weakness tracking — to fix your lowest-scoring chapters
Option 1: The Official CISI Workbook (Included)
The official CISI workbook is your source material, and for the IISI it is included in your exam fee — CISI provides the current edition when you book.
Strengths: Authoritative, complete, and the definitive reference for the syllabus.
Limitations: It is a reference text, not a practice tool. Reading it builds knowledge but does not train you to apply that knowledge — or work through the calculations — under exam conditions. This is a major reason so many workbook-only candidates fall into the 47% who fail.
Best for: Essential foundational reading (and you already have it, since it comes with the exam).
Option 2: Free PDFs and Sample Questions
Free question sets and PDFs floating around online can be a useful taster.
Strengths: Free, low commitment, good for a quick reality check.
Limitations: Usually small, often outdated, rarely aligned to the current syllabus, and typically lacking explanations — let alone worked calculations. They will not give you the volume or coverage needed to pass a 50-question exam spanning 10 chapters.
Best for: A first gauge of your readiness — like our free IISI sample questions — but not as your main prep.
Option 3: Classroom and Instructor-Led Courses
Some providers offer in-person or live online IISI courses.
Strengths: Structured, with an instructor to answer questions.
Limitations: The most expensive option by far, fixed schedules, and often heavy on lectures rather than the question practice that actually moves your score. Value depends heavily on the individual instructor.
Best for: Candidates who strongly prefer live teaching and have the budget and time.
Option 4: An Online Question Bank with Analytics
A dedicated question bank focuses on the exact skills the exam rewards: answering realistic questions, working through calculations, and learning from detailed explanations.
Strengths: Large volume of applied questions, full-chapter coverage, step-by-step calculation working, instant explanations, timed simulations, and analytics that show your weak chapters. This is the closest match to how the exam is actually tested.
Limitations: Best paired with the included workbook for source reading — the two work well together.
Best for: Candidates who want the most effective, exam-realistic preparation.

ExamPrep.ae's instant feedback and explanations help you understand each concept and improve your score.

Analytics that pinpoint your weakest chapters are one of the biggest advantages a good question bank offers.

The Verdict
The most effective approach for most candidates is the included official workbook for source reading, paired with an online question bank for applied practice. The workbook gives you the knowledge; the question bank trains you to apply it, work through the calculations, and shows you where you are weak. Before you commit, it is worth understanding exactly what the exam fee includes so you are not paying twice for materials you already have.
