Yamaguchi Prefectural Public High School Entrance Examination - Mathematics · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Numbers and Algebraic Expressions (数と式) & Equations and Inequalities / Functions (方程式・不等式、関数)

  • Expand and simplify 30 expressions involving monomials, polynomials, and the distributive law without a calculator, checking each answer by substitution.

  • Factor 25 quadratic expressions of the forms x²+(a+b)x+ab and a²−b², and explain in writing why each factorization is correct.

  • Compute with square roots: simplify 15 radical expressions and rationalize 10 denominators, stating the rule used at each step.

Your checkpoint

A 40-problem self-made worksheet on expansion, factorization, linear equations, and radicals, solved with at least 90% correct and every error annotated with its cause.

Week 2

Numbers and Algebraic Expressions (数と式) & Equations and Inequalities / Functions (方程式・不等式、関数)

  • Solve 15 linear inequalities and represent each solution set on a number line, including cases that flip the inequality sign.

  • Translate 10 short word problems into equations or inequalities and solve them, labeling the unknown clearly before writing the equation.

Week 3

Quadratic Functions and Proportional/Inverse Relations (関数 y=ax², 比例・反比例) & Equations and Inequalities / Functions (方程式・不等式、関数)

  • Sketch the graphs of y=ax² for five values of a and describe in writing how the sign and magnitude of a affect width and direction.

  • Convert 12 quadratic functions between standard form and vertex form by completing the square, and read off the vertex and axis of symmetry.

  • Determine the maximum or minimum value of 10 quadratic functions on a stated interval, distinguishing the vertex case from the endpoint case.

  • Solve 10 problems combining proportional and inverse proportional relations, including determining the constant of proportionality from given data.

Week 4

Quadratic Functions and Proportional/Inverse Relations (関数 y=ax², 比例・反比例) & Equations and Inequalities / Functions (方程式・不等式、関数)

  • Model and solve 8 rate, mixture, and motion problems that reduce to quadratic equations, rejecting extraneous roots with a written reason.

  • Solve 10 quadratic equations by factoring, completing the square, and the quadratic formula, and verify which method suits each form.

  • Interpret the discriminant for 10 equations and state the number of real solutions without fully solving.

  • Connect the intersection points of a line and a parabola to the solution of the corresponding simultaneous equations in 6 worked examples.
