About the HKDSE Maths M1 Exam
Mathematics Extended Part Module 1 (Calculus and Statistics) is an optional extension to the HKDSE Mathematics Compulsory Part, taken by students who need more mathematics for science, engineering, business and social-science pathways. It is assessed by a single public examination paper of 2 hours 30 minutes carrying 100 marks, made up entirely of conventional questions. The paper is split into Section A (50 marks, 8-12 short questions) and Section B (50 marks, 3-5 long questions), with all questions attempted. The syllabus covers a Foundation Knowledge area (binomial expansion, exponential and logarithmic functions), a Calculus area (differentiation, integration and their applications, plus the trapezoidal rule), and a Statistics area (binomial, geometric, Poisson and normal distributions, sampling and estimation). Results are reported on the HKDSE level scale and are used for university admission through JUPAS and, internationally, via UCAS tariff points.

Frequently Asked Questions
What is HKDSE Mathematics Module 1?
Module 1 (Calculus and Statistics) is one of two optional Extended Part modules of HKDSE Mathematics, taken in addition to the Compulsory Part. It emphasises applied calculus and probability/statistics and is popular with students heading into business, social sciences and life sciences.
How long is the M1 examination and how is it structured?
M1 consists of a single paper lasting 2 hours 30 minutes and carrying 100 marks. Section A has 50 marks (8-12 short questions) and Section B has 50 marks (3-5 long questions); candidates must attempt all questions, which are all conventional (long-answer), with no multiple-choice section.
How is M1 graded?
M1 is reported on the HKDSE seven-level scale with distinction sublevels: 5**, 5*, 5, 4, 3, 2, 1, and U (Unclassified) below Level 1. The Extended Part result is reported separately from the Compulsory Part level.
What is the difference between M1 and M2?
Module 1 (Calculus and Statistics) focuses on applied calculus and statistics (distributions, estimation), while Module 2 (Algebra and Calculus) focuses on pure algebra (mathematical induction, matrices, vectors) and more rigorous calculus. Students may take at most one of the two modules.
Are calculators allowed in the M1 exam?
Yes. Approved electronic calculators and mathematical drawing instruments may be used. Unless otherwise specified, numerical answers should be given exactly or correct to 4 decimal places.
How much does it cost to sit HKDSE M1 in 2026?
For the 2026 HKDSE, school candidates and permanent-HKID private candidates pay HK$519 per non-language subject such as M1; non-permanent-resident private candidates pay HK$1,119 per subject, plus a HK$595 initial fee for private candidates.
