When should you start doing HKSI Paper 1 mocks?

Two failure modes, and candidates split neatly between them. The first is starting mocks in week one, scoring badly on material never read, and concluding the exam is impossible. The second is treating the mock as a final exam and sitting the first one four days before the real thing, when nothing it reveals can still be fixed.

The gate between them is simple and it is not about a date.

The readiness gate

Sit your first full mock once you have read all nine topics at least once. Not learned them. Read them. A mock before that point is measuring the topics you have not opened yet, which you already know about, and it costs you ninety minutes to find out.

There is a separate tool for the very beginning, and it is not a mock. A short diagnostic of ten questions tells you which topics are empty and takes four minutes. Use that in week one if you want a baseline. Do not use a full paper for it.

A schedule for each plan length

The two-week column is a rescue plan, not a recommendation. It works only if you can put the hours in and it leaves no room for a bad week. There is a fuller treatment of scheduling in the revision schedule.

Why not earlier?

Three reasons, and the third is the one that matters.

• A mock on unread material teaches you nothing you did not already know, and it burns a mock form you cannot use again as a clean measurement.
• Early mocks produce demoralising scores at the point in preparation where motivation is most fragile.
• Full papers are a scarce resource. Most candidates have access to a handful of clean forms at most, and spending one to confirm that you have not read Topic 7 yet is a poor trade.

That third point drives the whole schedule. Treat unseen mock forms as consumable, because they are.

Why not later?

Because a mock is diagnostic, and a diagnosis is only useful if there is time to act on it. Sit your first full paper with three weeks left and a weak topic is a fixable problem. Sit it with three days left and the same weak topic is just something you now feel anxious about.

There is also a pacing argument. The 1.5-minute average across 60 questions in 90 minutes is a rhythm you have to build, and building it takes more than one attempt. Candidates who sit a single mock almost always discover the clock in the last twenty questions of the real thing.

What if your first mock score is terrible?

Expect it to be. First mocks come in below the pass mark for most people, and that is what a first mock is for. The pass mark is 42 of 60, and the published twelve-month mean pass rate to June 2026 was 51.9%, so a first attempt landing in the thirties puts you exactly where a large share of candidates start.

What matters is the shape of the score, not the number. Break it down by topic. A flat score of low marks everywhere means you need more reading. A score that is fine in six topics and poor in three means you need three focused weeks, which is a much better position and a much clearer plan.

One thing we would do differently from most providers

The conventional advice is to save all your mocks for the end. We think that is wrong, and the reason is that mocks are the only tool that trains retrieval under uncertainty, which is the actual skill being tested. Front-load one earlier than feels comfortable, right after your first successful mixed set, and use the remaining forms across the final weeks rather than stacking them in the last few days.

The concession is that this only works if you have enough unseen forms. If you have two, save them. If you have five, spread them. Our own course carries 5 forms built from 65 questions that never appear in the practice modules, which is what makes spreading them possible, and a candidate working from a smaller pool should be more conservative.

The mechanics of sitting and reviewing one are in mock exam strategy.
