May/June 2024 Cambridge IGCSE (0607) Exam Analysis
The May/June 2024 series for International Mathematics (0607) presented a well-calibrated challenge across both the Core and Extended pathways. Paper 1 and Paper 2 maintained their focus on rapid-recall and non-calculator fluency, while the longer structured papers (Paper 3 and Paper 4) demanded strong stamina and the precise application of graphic display calculators (GDC). The specialized investigative papers (Paper 5 and Paper 6) tested students' capability to recognize patterns, formulate mathematical generalisations, and apply modeling constraints to real-world scenarios such as carbon footprints.
Where the Marks Were Won and Lost
In the non-calculator papers, standard questions on Venn diagrams, indices, and basic fractional arithmetic served as excellent confidence builders. However, significant marks were lost in coordinate geometry and advanced spatial reasoning. For instance, the stretch transformation in Paper 2 Question 16 tripped up many candidates who struggled to correctly determine the scale factor and identify the invariant line \( x = -1 \). In Paper 4, multi-step probability questions involving selection without replacement and 3D trigonometry (such as finding the sine of angle PAN in a cuboid) separated high-achievers from the rest of the cohort.
Strategic Advice for Future Candidates
- Master your GDC: Do not rely on manual sketches for reciprocal functions and asymptotes. Practice inputting rational equations with vertical and horizontal asymptotes to easily read intersections.
- Be Precise with Set Notation: Distinguish clearly between union, intersection, and complements, especially when translating shaded regions of Venn diagrams into algebraic set notation.
- Investigate Systematically: For Papers 5 and 6, write down consecutive differences in tabular data to quickly identify linear \( (an + b) \) or quadratic differences. This systematic approach is vital for securing final generalisation marks.
