Key examiner messages
Top priorities from the principal examiner before you revise
As expected in the Applications and Interpretation pathway, Statistics and Probability took center stage, accounting for a massive 51 marks.
Major chunks of these marks resided in Paper 2 Question 1 (linear regression on global temperatures) and Question 4 (probability trees and binomial distribution).
Calculus followed closely with 36 marks, heavily weighted towards optimizing the cost of constructing containers and applying the trapezoidal rule to area approximation.
Functions and Geometry/Trig were also significant, leaving Number and Algebra as the least tested domain with only 5 marks directly dedicated to financial compound interest.
Compare difficulty across recent years. Compare topic weight by year to spot recurring and returning areas.

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “Find” questions.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “down” questions.
Match the expected response style for “State” questions.
Match the expected response style for “Determine” questions.
Match the expected response style for “Show” questions.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Support your choice with specific evidence from data or the scenario given.
