Frequently Asked Questions (FAQs)

1. Why are grade boundaries different for each paper?

Each paper tests distinct skills: conceptual understanding, calculations, and practical reasoning. Boundaries reflect relative difficulty and historical performance.

2. How is the final grade calculated?

All components combine into a mark out of 100. Excellence in one paper cannot fully compensate for weaknesses in another. Balanced preparation is essential.

3. Which component is often the hardest?

Many students find Paper 2 challenging due to its volume of calculations and problem-solving demands. Consistent practice improves speed and accuracy.
