Exam tips
Paper format
- Duration
- 70 min
- Total marks
- 100
- Weighting
- 100%
- Question types
- Algebra, quadratic functions, measurement, trigonometry and data analysis
- Factorization, expansion, completing the square and inequality manipulation should be automatic. Slow algebra drains time from interpretation items.
- For every quadratic, write: vertex, axis, intercepts, discriminant and domain. Most questions use one of these five facts.
- A rough graph prevents sign and range errors. Mark the axis of symmetry and whether the parabola opens upward or downward.
Common mistakes
Quadratics
Using discriminant conclusions without considering tangency or domain restrictions.
How to avoid: After calculating D, check whether intersections lie inside the given domain.
Inequalities
Forgetting to reverse the inequality sign when multiplying or dividing by a negative.
How to avoid: Mark negative operations with an arrow before rewriting the inequality.
Trigonometry
Using the wrong side for sine, cosine or tangent.
How to avoid: Label sides relative to the given angle, not relative to the drawing orientation.
