What this paper assessed
Mathematics Advanced is one paper of 100 marks across 180 minutes. Section 1 is 10 multiple choice (10 marks). Section 2 is long response (90 marks). The 2025 paper kept the established weighting across functions, calculus, financial maths and statistics.
Section strategy
Section 1 in 15 minutes. Section 2 at roughly 1.8 minutes per mark. The most common time loss in 2025 was candidates spending too long on a single late question; if a part stalls for more than four minutes, move on and return later.
Common errors flagged
The 2025 NESA notes from marking centre flagged careless differentiation of products and quotients, weak setup of probability tree diagrams, and finance questions where candidates used annual rates without converting to the relevant compounding period.
What to do with this paper
