HKDSE Maths M2 study plan

HKDSE Maths M2 · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Algebra (Extended Part Module 2)

  • Recall and apply the binomial theorem for positive integral indices, including finding a general term and a specific coefficient in an expansion of the form (a + b)^n

  • Compute and manipulate factorials, permutations and combinations, and solve counting problems involving arrangements with and without repetition

  • Expand and simplify expressions involving sigma notation, and prove simple summation identities by induction

  • State and apply the principle of mathematical induction to prove statements about sums, divisibility and inequalities

Your checkpoint

A one-page formula sheet plus 12 self-written induction and binomial questions with full worked solutions, self-marked against the marking scheme style of showing the induction hypothesis explicitly

Week 2

Algebra (Extended Part Module 2)

  • Perform polynomial long division and synthetic division, and state the quotient and remainder correctly

  • Apply the remainder theorem and factor theorem to find unknown coefficients in a polynomial

  • Solve polynomial equations with complex roots and use conjugate root pairs to reconstruct a polynomial

  • Manipulate complex numbers in rectangular and polar form, including modulus, argument and de Moivre's theorem

Your checkpoint

A worked portfolio of 10 polynomial and complex-number problems, including at least 3 that require finding unknown constants from given remainder or root conditions, with error log of mistakes made

Week 3

Algebra (Extended Part Module 2)

  • Solve systems of linear equations in three unknowns using Gaussian elimination and interpret the solution set geometrically

  • Compute 2x2 and 3x3 determinants and inverses, and use them to solve matrix equations of the form AX = B

  • Apply matrix operations to represent transformations and verify properties such as associativity and non-commutativity

  • Set up and solve word problems that reduce to a system of linear equations

Your checkpoint

A timed 45-minute set of 8 matrix and system questions completed in one sitting, fully corrected and annotated with the cause of each lost mark

Week 4

Algebra (Extended Part Module 2) & Calculus (Extended Part Module 2)

  • Compute limits of rational, surd and trigonometric functions algebraically, including one-sided limits and limits at infinity

  • Determine continuity of a piecewise function at a point and find unknown constants that make a function continuous or differentiable

  • Differentiate from first principles and state the derivative rules for powers, products, quotients and the chain rule

  • Differentiate implicit and parametric functions and find second derivatives

Your checkpoint

A closed-book mid-point test of 10 questions covering induction, polynomials, matrices and differentiation, scored and compared against a target of 70 percent, with a written list of the three weakest sub-skills

Week 5

Calculus (Extended Part Module 2)

  • Apply differentiation to find tangents, normals and stationary points, and classify them using the first or second derivative test

  • Solve rates of change and related rates problems by setting up the connecting equation before differentiating

  • Locate maxima and minima in applied optimisation problems and justify the answer with a derivative test

  • Sketch curves accurately using intercepts, asymptotes, stationary points and symmetry

Your checkpoint

A set of 8 applications-of-differentiation problems, including 2 related rates and 2 optimisation word problems, each with a labelled sketch and a written justification sentence for every extremum

Week 6

Calculus (Extended Part Module 2)

  • Integrate standard functions and use substitution to evaluate indefinite and definite integrals

  • Evaluate definite integrals by parts and by partial fractions, choosing the method before starting

  • Apply integration to find areas between curves and volumes of revolution about the x-axis

  • Use the fundamental theorem of calculus to differentiate integrals with variable limits

Your checkpoint

A worked solutions booklet of 12 integration problems, with at least 3 area or volume problems, showing the setup integral before evaluation and the substitution limits stated explicitly

Week 7

Calculus (Extended Part Module 2)

  • Solve first-order separable differential equations and apply an initial condition to find the particular solution

  • Model and solve simple growth, decay and cooling problems using differential equations

  • Evaluate limits using L'Hopital's rule where appropriate and recognise when it does not apply

  • Combine calculus techniques to answer multi-step examination-style questions under time pressure

Your checkpoint

Two timed 50-minute mock papers covering both domains, marked strictly, with a table of marks lost by topic and a plan for the final week based on that table

Week 8

Algebra (Extended Part Module 2) & Calculus (Extended Part Module 2)

  • Re-solve every question previously logged as an error until each is correct without notes

  • Complete a full-length timed mock under examination conditions and manage time allocation across both domains

  • State and apply the key formulas for binomial expansion, matrices, differentiation and integration from memory in a rapid recall drill

  • Identify and fix the two highest-frequency remaining error types from the mock analysis

Your checkpoint

A completed full-length mock with a score report, plus a corrected error log showing every previously wrong question re-attempted successfully

Milestones

Week 2: Can state the induction hypothesis and complete the inductive step unaided for a divisibility and a summation proof, and can find an unknown coefficient using the remainder theorem, in under 15 minutes each

Week 4: Scores at least 70 percent on the closed-book mid-point test covering induction, polynomials, matrices and differentiation, with no more than one arithmetic slip

Week 6: Can set up and evaluate an area-between-curves integral and a substitution integral correctly on the first attempt, and explains why each chosen method applies

Week 8: Scores at least 75 percent on the full-length timed mock and has cleared the entire error log with no unresolved question
