Parisel Exam Insight
A student-friendly view of question patterns, syllabus coverage and response demands across 17 reviewed Chemistry papers.
Use these patterns to choose what to practise. They describe the papers reviewed; they do not predict the next paper.
Across the papers
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.
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.
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.
Selected high-weight areas
These are the highest-weight reviewed areas in this view. They are useful highlights, not a complete paper breakdown, and one question may connect to more than one area.
Acids and redox reactions
Organic synthesis
Structure and properties
Chemical equilibrium
Analytical techniques
Reviewed evidence
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
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.

Reviewed marks for the selected high-weight areas. Darker cells show greater reviewed weight within this view.
| Selected high-weight area | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|---|
| Acids and redox reactions | 49 | 44 | 44 | 52 | 58 | 50 |
| Organic synthesis | 48 | 26 | 32 | 25 | 36 | 28 |
| Structure and properties | 20 | 27 | 24 | 27 | 38 | 26 |
| Chemical equilibrium | 39 | 20 | 16 | 25 | 20 | 13 |
| Analytical techniques | 15 | 27 | 1 | 13 | 3 | 13 |
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.
Question labels connected to each selected high-weight area. A question can appear in more than one row.
