Across the papers

01

The paper structure varies over time

Complete papers range from 100 to 120 marks, with 12 to 38 assessed parts.

Practise: Prepare for the recurring paper shape while using the content and question trends to decide what to practise.

02

Chemical knowledge application is the leading recurring capability

This capability is associated with 556 reviewed marks across 159 parts over 6 years.

Practise: Practise chemical knowledge application in several topics and response formats, rather than treating it as a one-off question type.

03

Short response questions are more prominent in the latest paper

Their mark share changes from 4% in 2020 to 45% in 2025.

Practise: Include short response practice in your revision plan, while checking the year-by-year weighting.

Reviewed evidence

What this page can tell you

  • Which syllabus areas recur in the reviewed questions.
  • How reviewed marks and question labels move across the years.
  • Where the paper structure changes around a stable content base.

This page summarises reviewed questions and their syllabus links. It is a descriptive guide, not a complete mark allocation or an official assessment breakdown.

How to use this

Turn the pattern into practice

Start with a mixed paper. When you review it, sort missed marks by syllabus area and response demand—not only by topic.

Best next move: use the year views below to choose a recurring area and practise it in a different question context.

A blank cell means no reviewed mark was recorded for that area in that year. These selected-area marks are not an additive paper total and may overlap when a question connects to more than one area.
