Why people fail HKSI Paper 1

Roughly half the room does not pass. The twelve-month mean to June 2026 was 51.9%, which puts the implied fail rate at about 48.1%, and that is a striking figure for an exam with no calculations in it.

Failure here is rarely mysterious. It has about six recognisable shapes, and most people who fail can identify theirs within a minute of reading the list.

1. Treating 70% like a normal pass mark

This is the big one. Most professional exams pass you at 50% or 60%. Paper 1 wants 42 of 60, and there is no compensation, no scaling you can rely on, and no partial credit anywhere. A candidate who genuinely knows two-thirds of the syllabus is not borderline. They have failed already, and they usually find out on the day.

Those figures are illustrative arithmetic, not published data. The point they make is structural: at a 70% threshold, breadth beats depth, because a topic you skipped cannot be rescued by a topic you mastered.

2. Skipping a topic entirely

Topic 8 is the usual casualty. Accessing public capital, listing rules, takeovers - furthest from most people's jobs, small enough to look optional. Topic 2 gets dropped for the opposite reason: it is short, so it feels like it does not matter. Both decisions trade a couple of evenings for marks you cannot get back.

3. Reading and calling it revision

The most common preparation failure, and the hardest to see from the inside. Reading produces the sensation of familiarity. Familiarity feels like knowledge. Then a question puts four plausible options in front of you and asks which one is right, and recognition collapses because you never practiced making the distinction.

Our opinion: after your first pass through a topic, more than half your remaining time on it should be questions with the answers checked against the source. Not reading. Not highlighting. Questions.

4. Never sitting a full paper against the clock

Ninety minutes, 60 questions, 1.5 minutes each. People who have not rehearsed the pacing lose marks at both ends - overthinking the early stems, then panic-guessing a block of ten at the finish. A timed mock also reveals something reading never does: that your accuracy drops in the last twenty minutes. That is a stamina problem with a training solution, and you cannot fix it if you never discover it.

5. Underestimating Topic 4

Licensing and registration and the subsidiary legislation around it looks like administration. It is dense, examinable detail - which regulated activity needs which licence, client money against client securities, records, contract notes, capital. It is the classic multiple-choice topic and it is heavily weighted on our estimate of the paper's shape.

Meanwhile Topic 3 absorbs everyone's anxiety and a disproportionate share of their hours. We have written about that imbalance in the hardest topics on Paper 1, and it is the single most correctable mistake on this list.

6. Studying from the wrong syllabus version

Paper 1 runs on syllabus v3.5. Second-hand notes and old PDFs circulate freely, and a set written against an earlier version will teach you a structure the current paper does not use. Check the version number on the front page of whatever you are reading. It takes ten seconds.

What failing actually costs

The concession: some people fail for none of these reasons. They knew the material, had a bad ninety minutes, and missed by two. That happens, and at a 70% threshold it happens more than it would at 60%. If that was you, the fix is not more reading - it is a plan for the second attempt that targets pacing rather than content.
