Google searches for CISI Introduction to Securities and Investment past papers often mix three different things: the UK exam, the International Introduction to Securities & Investment (IISI), and informal question files with no version. A useful practice plan begins by separating them.

Quick answer: For the UK Version 26 exam, use official samples to learn the style, current chapter questions to build knowledge and unseen 50-question, 60-minute mocks to test readiness. Do not treat an international or undated paper as a UK past paper.

Step 1: confirm the exact exam

The UK qualification page may use Introduction to Investment, while the workbook and syllabus use Introduction to Securities & Investment. The international exam adds an extra “International” and is commonly shortened to IISI.

Check the full name, qualification route and syllabus topics. A paper containing UK ISAs, UK taxation and UK regulatory redress is not interchangeable with a global IISI paper. Conversely, a generic international paper will not fully prepare you for those UK chapters.

Step 2: confirm the syllabus version

Version 26 applies from 1 August 2026 to 31 July 2027. The 11 areas and question numbers are:

Syllabus area	Questions
Financial-services sector	3
Economic environment	4
Equities	9
Bonds	7
Other markets and investments	4
Derivatives	4
Investment funds	6
Regulation and professional integrity	4
Taxation, wrappers and trusts	4
Other financial products	2
Financial advice	3

Version 26 contains official updates in areas including FSCS protection, FCA objective wording and ISA treatment. An older question may still be useful for bond mechanics but wrong for a current threshold. Version-check at question level, not merely at file level.

Step 3: use different questions for different jobs

Official sample questions: learn presentation

Official samples help you see how questions and answer options are expressed. They are a starting point, not a complete measure of the live exam’s breadth or difficulty.

Chapter questions: build and diagnose knowledge

Use short sets immediately after study. The goal is to identify the exact objective you have not mastered. Complete the explanation before moving on, even when you guessed correctly.

Mixed question blocks: practise identification

In a chapter set, you know the subject. In a mixed set, you must decide whether a scenario concerns an equity, bond, derivative, fund, regulatory rule or advice process. That first classification is part of the exam skill.

Full mocks: measure performance

A final-stage mock should reproduce 50 questions in 60 minutes, use mixed order and cover all 11 elements. Keep the set unseen until you sit it. Repeating a familiar mock can be helpful for retention but should not count as independent evidence of readiness.

What to reject

Avoid any file or website that:

• labels questions “real exam dumps” or encourages memorising live items;
• does not identify UK ISI versus IISI;
• gives no syllabus version or update date;
• provides answers without explanations;
• concentrates on a few easy definitions while omitting regulation, tax or advice;
• uses regulatory thresholds that cannot be checked against a current source.
• cannot identify the exam, syllabus version or question source. At most, label such a paper “calculation only” for stable arithmetic; do not use it for current UK tax, regulatory responsibilities or a scored mock.

The problem is not only legitimacy. Poor questions train poor reasoning.

A four-week practice schedule

This plan assumes you have already begun reading the workbook.

Week 1: markets foundation

Complete focused questions on the financial sector, economics, equities and bonds. For every error, write the concept in your own words and one contrast—for example, primary versus secondary market or coupon rate versus yield.

Week 2: products and funds

Practise other investments, derivatives and collective funds. Use comparison tables for rights, obligations, liquidity, return and risk. Add simple calculations or price-and-yield reasoning where the syllabus requires them.

Week 3: UK regulation and personal finance

Use only current questions for regulation, FSCS, taxation, ISAs, pensions, trusts, mortgages and protection. These are the areas most vulnerable to outdated materials. Finish the week with mixed 20-question blocks.

Week 4: advice and full mocks

Review the client-advice process, then sit full mocks. Leave correction time between attempts. Your next session should be determined by the last mock’s errors, not by the next chapter in a generic timetable.

A useful error taxonomy

Code	Error	What to do
K	Knowledge	Return to the exact learning objective and test it again later
C	Confusion	Compare the two concepts side by side
V	Version	Replace the question or verify the current fact
R	Reading	Identify the qualifier or fact you missed
A	Application	Explain why the rule fits this scenario
T	Time	Practise a smaller block at live pace

Review guessed answers as well as wrong answers. A lucky correct choice can hide the same weakness that produces a wrong answer later.

How high should mock scores be?

The live pass mark is 70%, but one familiar 70% is weak evidence. Look for repeated passes on fresh sets, balanced chapter performance and completion within one hour. A reasonable safety margin is more useful than targeting the minimum, but explanation quality matters as much as the number.

Keep practice aligned to 2026

Always compare regulatory and tax questions with the current syllabus and CISI candidate updates. A past question is not an authority when the underlying fact has changed.

The CISI Introduction to Securities & Investment UK course covers the current exam format and all 11 Version 26 areas.

Bottom line

Do not judge a practice source by whether it calls itself a past paper. Judge it by whether it is the correct UK exam, the correct version, balanced across the syllabus and supported by explanations. The goal is to answer new questions from understanding—not to recognise an old PDF.
