Mathematics HKDSE Free Practice Test

Q: What is included in Math Premium?

Premium opens a guided route for Mathematics: higher-volume topic practice, timed sets, active-recall flashcards, spaced rechecks, saved mistake review, complete worked explanations, cross-device history, and dashboard progress. AceDSE uses these tools as one study loop, so students can move from a weak-topic signal to focused practice and then verify whether the weakness has improved.

Q: How is the next practice tailored to the student?

AceDSE uses the student's answers, pace, repeated weak topics, saved mistakes, and recent review history to recommend the next useful focus. The purpose is not to label a student permanently: recommendations change as new answers show improvement or expose another gap, and the student can still choose a different topic or timed set at any time.

Q: How can Premium save revision time?

Students spend less time searching through random worksheets, travelling to collect exercises, or deciding what to do next. A short diagnostic and the saved progress signals point to a focused set, while explanations, rechecks, and mistake review stay in the same workspace. Students can use short study blocks at home, between lessons, or while travelling and continue at their own pace.

Q: Do Premium questions include useful explanations?

Yes. Published practice includes a complete explanation designed to show why the correct answer works, the key exam method or evidence, and the common trap behind plausible wrong choices where relevant. Explanations are quality-checked and may be corrected when a verified content issue, syllabus change, or clearer solution method is identified.

Q: What progress appears in the dashboard?

For the selected Premium subject, the signed-in dashboard can show completed practice, recent activity, study streak, repeated weak topics, saved mistakes, review history, and readiness signals. These indicators help students and an optional read-only parent view decide what needs attention next; they are study guidance, not an official predicted DSE grade.

Q: Does 8,000+ mean every subject has 8,000 Premium questions?

No. 8,000+ is the owner-supplied platform-wide Premium practice inventory across AceDSE, not a promise of 8,000 questions in every subject. Subject catalog cards show separately verified counts where those counts are available; checkout availability does not turn the platform-wide figure into a per-subject promise.

Q: Does one subscription include every subject?

No. Each HKD 399/month subscription unlocks one selected subject. The subject shown in Stripe Checkout is the subject added to that account. Opening another subject requires its own subscription, so always check the subject name before confirming.

Q: How does the 3-day trial, billing, and cancellation work?

Stripe shows the selected subject, trial end, and HKD 399 monthly price before confirmation. Unless cancelled first, the initial charge is scheduled for the displayed trial end and the subscription then renews monthly until cancelled. Use Manage subscription in the signed-in dashboard to open Stripe's secure portal; cancel before the trial end to avoid the first scheduled charge.

Q: What can I use without Premium?

Every subject has exactly 30 free questions. Questions 1–6 show immediate feedback; Questions 7–30 preserve test focus. After all 30, an email unlocks the complete on-page answer review and five subject-specific study emails. Local progress, the exam blueprint, and the syllabus map remain free, with no payment card.

Q: Is Premium checkout available for this subject?

Mathematics is currently a supported Premium subject. If live checkout or immediate access delivery is temporarily unavailable, AceDSE sends you to the subject-aware pricing information instead of attempting a payment that may not deliver access.

2027 assessment blueprint

Know what the real Mathematics assessment includes

AceDSE's free questions are a short multiple-choice diagnostic. They check selected concepts; they are not a past paper, predicted paper, or complete simulation of every assessed skill.

65% Compulsory Part Paper 1 · Conventional questions

35% Compulsory Part Paper 2 · Multiple choice

• Extended Part · M1 or M2 conventional paper

CP, M1 and M2 are separate study routes; an MCQ check cannot represent the whole assessment.

Algebra laws

Keep the operation visible: products, quotients, powers, and logarithms should not be buried inside one sentence.

Indices

Multiply powers

a^m\cdot a^n=a^{m+n}

Divide powers

\frac{a^m}{a^n}=a^{m-n}

Power of a power

(a^m)^n=a^{mn}

Zero index

a^0=1\quad(a\ne0)

Same-base rules. Keep the base; operate on the indices.

Logarithms

Product law

\log_a(xy)=\log_a x+\log_a y

Quotient law

\log_a\!\left(\frac{x}{y}\right)=\log_a x-\log_a y

Power law

\log_a(x^n)=n\log_a x

Use when $a>0$ , $a\ne1$ , and all log inputs are positive.

Quadratic equations

Separate the formula from the discriminant so students can check the root conditions before solving.

Quadratic formula

Standard form

ax^2+bx+c=0\quad(a\ne0)

Solutions

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

The whole denominator is $2a$ ; keep the $\pm$ sign.

Discriminant

Definition

\Delta=b^2-4ac

Root count

\begin{cases}\Delta>0&\text{two distinct real roots}\\ \Delta=0&\text{repeated real root}\\ \Delta<0&\text{no real roots}\end{cases}

Use the sign of $\Delta$ before deciding how many real roots there are.

Sequences

Put the general term, finite sum, and infinity condition on their own lines for quick comparison.

Arithmetic sequence

General term

u_n=a+(n-1)d

Sum of first n terms

S_n=\frac{n}{2}\{2a+(n-1)d\}

$a$ is the first term and $d$ is the common difference.

Geometric sequence

General term

u_n=ar^{n-1}

Finite sum

S_n=\frac{a(1-r^n)}{1-r}\quad(r\ne1)

Sum to infinity

S_{\infty}=\frac{a}{1-r}\quad(|r|<1)

$S_{\infty}$ only applies when the common ratio satisfies $|r|<1$ .

Focus session

Run a timed Math study block

Pick a short timer, keep the checklist visible, and turn the free questions into a real revision session instead of a quick scroll.

Premium FAQ

What students get—and how the subscription works

Open any question to understand the study benefits, tailored route, explanations, dashboard, price, trial, cancellation, and subject availability.

What is included in Math Premium?

Premium opens a guided route for Mathematics: higher-volume topic practice, timed sets, active-recall flashcards, spaced rechecks, saved mistake review, complete worked explanations, cross-device history, and dashboard progress. AceDSE uses these tools as one study loop, so students can move from a weak-topic signal to focused practice and then verify whether the weakness has improved.

How is the next practice tailored to the student?

AceDSE uses the student's answers, pace, repeated weak topics, saved mistakes, and recent review history to recommend the next useful focus. The purpose is not to label a student permanently: recommendations change as new answers show improvement or expose another gap, and the student can still choose a different topic or timed set at any time.

How can Premium save revision time?

Students spend less time searching through random worksheets, travelling to collect exercises, or deciding what to do next. A short diagnostic and the saved progress signals point to a focused set, while explanations, rechecks, and mistake review stay in the same workspace. Students can use short study blocks at home, between lessons, or while travelling and continue at their own pace.

Do Premium questions include useful explanations?

Yes. Published practice includes a complete explanation designed to show why the correct answer works, the key exam method or evidence, and the common trap behind plausible wrong choices where relevant. Explanations are quality-checked and may be corrected when a verified content issue, syllabus change, or clearer solution method is identified.

What progress appears in the dashboard?

For the selected Premium subject, the signed-in dashboard can show completed practice, recent activity, study streak, repeated weak topics, saved mistakes, review history, and readiness signals. These indicators help students and an optional read-only parent view decide what needs attention next; they are study guidance, not an official predicted DSE grade.

Open the dashboard

Does 8,000+ mean every subject has 8,000 Premium questions?

No. 8,000+ is the owner-supplied platform-wide Premium practice inventory across AceDSE, not a promise of 8,000 questions in every subject. Subject catalog cards show separately verified counts where those counts are available; checkout availability does not turn the platform-wide figure into a per-subject promise.

Does one subscription include every subject?

No. Each HKD 399/month subscription unlocks one selected subject. The subject shown in Stripe Checkout is the subject added to that account. Opening another subject requires its own subscription, so always check the subject name before confirming.

How does the 3-day trial, billing, and cancellation work?

Stripe shows the selected subject, trial end, and HKD 399 monthly price before confirmation. Unless cancelled first, the initial charge is scheduled for the displayed trial end and the subscription then renews monthly until cancelled. Use Manage subscription in the signed-in dashboard to open Stripe's secure portal; cancel before the trial end to avoid the first scheduled charge.

Cancellation and refund information

What can I use without Premium?

Every subject has exactly 30 free questions. Questions 1–6 show immediate feedback; Questions 7–30 preserve test focus. After all 30, an email unlocks the complete on-page answer review and five subject-specific study emails. Local progress, the exam blueprint, and the syllabus map remain free, with no payment card.
