The hardest topics in HKSI Paper 1, and why they catch people

Compiled by the Sitonce editorial team from the HKSI and SFC sources listed belowUpdated 6 min readFacts verified 5 September 2026
The short answer

Topic 3, the Securities and Futures Ordinance, is the hardest to read. Topic 4, licensing and subsidiary legislation, is the heaviest on our estimate at about 14 of 60 questions, against about 8 for Topic 3. Hardest and biggest are not the same topic here. Topic 8 is the most commonly skipped. These weightings are our estimate, not published by HKSI.

Topic 3 and Topic 4 between them are, on our estimate, roughly 8 and 14 of the 60 questions - call it a third of the paper. They are also the two that candidates describe as the worst. That combination is what makes them dangerous - not that they are hard in isolation, but that being weak on them is arithmetically close to being unable to pass.

These weightings are our estimate

HKSI does not publish how many questions come from each topic. The counts below are ours, derived by scaling each topic's share of the 66 second-level syllabus headings to 60 questions. Use them to allocate study time, not as a fact about your paper.

Why is Topic 3 the hardest?

Because it is not a subject. It is a filing system.

Topic 3 walks the Securities and Futures Ordinance from the preliminary Part through to disclosure of interests, taking in the SFC's own constitution, exchanges and clearing houses, offers of investments, licensing, client assets and records, business conduct, supervision and discipline, investor compensation, and market misconduct along the way. Eleven second-level headings. Each one is a Part or a cluster of Parts, and the exam expects you to know which subject lives where.

The trap is that Topic 3 overlaps with almost everything else. Licensing appears here and again in Topic 4. Business conduct appears here and again in Topic 5. Market misconduct appears here and again in Topic 9. Candidates read Topic 3, feel the repetition, and conclude they can skim it because it will come up later. Then the question asks which Part of the Ordinance a provision sits in, and later never helped.

Do not memorise section numbers, incidentally. The exam works at the level of Part and subject, and chasing section numbers is a way to spend six hours getting nothing. If a number ever looks load-bearing, check the current text on e-Legislation rather than trusting a study note.

Why Topic 4 is the one that actually decides your result

Topic 3 gets the fear. Topic 4 gets the marks.

Licensing and registration plus subsidiary legislation is, on our estimate, 10 questions, and it is dense with the kind of detail that multiple choice loves: which regulated activity requires which licence, the difference between a licensed corporation and a registered institution, capital requirements, client securities against client money, record-keeping periods, contract notes and statements of account, audit obligations. Every one of those is a clean four-option question with three plausible distractors.

Our opinion, and it is the main thing we would tell a candidate: most people over-prepare Topic 3 and under-prepare Topic 4, and the syllabus structure is why. Topic 3 looks intimidating so it gets the anxiety and the hours. Topic 4 looks like admin so it gets skimmed. The paper does not share that sense of drama.

The underrated one: Topic 8

Accessing public capital - listing rules, other listed securities, takeovers and share buy-backs, SFC-authorised products, alternative routes to public money. On our estimate it is around 5 questions, which is small enough to skip and large enough to hurt.

It catches people because it is the topic furthest from most candidates' day jobs. If you work on a dealing desk you will never touch the Takeovers Code. Unfamiliarity plus low weighting equals the topic everyone leaves until the night before, and then does not do.

Which topics can you treat lightly?

Topic 2, on our estimate, is about 2 questions - an outline of Hong Kong's legal system and the Companies Ordinance basics. Read it once, do the practice questions, move on. Topic 1 at around 5 questions is a regulatory overview that most of the rest of the syllabus re-teaches you anyway, so it tends to look after itself.

The concession: because the weightings are our estimate and not published, a paper that happens to lean towards Topic 7 or Topic 9 will make our advice look wrong on the day. Sampling varies. The estimate is a guide to where to put your hours, not a promise about your specific form.

How to attack the hard two

  • Learn Topic 3 as a map before you learn it as content. Write the Parts down in order, with one line each, and be able to reproduce that list from memory. Everything else attaches to it.
  • Do Topic 4 in pairs. Client money and client securities together. Licensed corporation and registered institution together. The exam tests the boundary, so learn the boundary.
  • Question-first on both. Attempt the questions before you feel ready and let the wrong answers tell you what to reread. Our set of Paper 1 practice questions by topic is built for this order of operations.
  • Give Topic 8 one honest evening rather than zero. Five marks is the difference between 42 and a resit.

If you want the full ordering rather than just the worst offenders, we rank all nine in our topic-by-topic difficulty ranking.

Common questions

What is the hardest topic in HKSI Paper 1?

Topic 3, the Securities and Futures Ordinance. It spans the whole Ordinance from the preliminary Part to disclosure of interests across eleven second-level headings, and it overlaps with several other topics, which encourages candidates to skim it. On our estimate it is also the heaviest topic on the paper.

How many questions come from each Paper 1 topic?

HKSI does not publish a question breakdown by topic. The figures we use are our own estimate, scaled from each topic's share of the 66 second-level syllabus headings to 60 questions. They are useful for allocating study hours and should not be treated as the real blueprint.

Do I need to memorise SFO section numbers?

No. Paper 1 works at the level of Parts and subjects rather than section numbers, and memorising numbers is a poor use of study time. Learn which Part covers licensing, which covers business conduct, and which covers market misconduct, and you have what the exam wants.

Which topic do candidates most often skip?

Topic 8, accessing public capital. It sits furthest from most candidates' day-to-day work, and its estimated weighting of around five questions makes it feel skippable. Five questions is roughly the margin between passing and resitting, so it is a poor thing to gamble.

Is Topic 2 worth studying at all?

Briefly, yes. On our estimate it carries only about two questions, but it is the shortest topic in the syllabus and can be covered in one sitting. Skipping it saves an evening and risks two marks, which is bad value at a 70% pass mark.
