Q: What does H2 Chemistry Paper 4 Format cover?
A: Get a detailed look at the 2026 H2 Chemistry Paper 4 practical paper-its planning, PDO/ACE, and qualitative analysis components-and learn how to train for the two-and-a-half-hour, 50-mark exam.
Exam snapshot Paper 4 | 2 h 30 min | 50 marks | 20 % of the overall H2 Chemistry grade
Paper 4 assesses laboratory planning, data handling, evaluation, and qualitative analysis. The 2026 specimen paper mirrors the new emphasis on spreadsheet-style processing and clear communication of uncertainty. Advance preparation-both in the lab and on paper-is key to scoring consistently.
Status: SEAB H2 Chemistry (9476) syllabus and specimen paper last checked 2026-01-13 (PDF last modified 2026-01-13). Paper 4 is 2 h 30 min, 50 marks, weighting 20 %, with Planning at 4 % and MMO/PDO/ACE at 16 % combined.
Syllabus code note: SEAB’s 2026 specimen set is labelled 9476. SEAB also lists 9729 as “last year of exam in 2026”, so older resources may still use that code.

1 Structure Overview
- Scheme of assessment (SEAB 9476): 2 h 30 min, 50 marks; Planning carries 4%, MMO/PDO/ACE carry 16% combined. Scope covers titration, gravimetric work, gas collection, thermochemistry, kinetics, qualitative analysis, and simple organic synthesis/purification.
- Specimen pattern: The 2026 specimen paper (9476/04) totals 50 marks and groups tasks into planning, data processing/evaluation, and qualitative analysis.
- Qualitative analysis notes (tests and expected results) are printed at the back of the Paper 4 booklet for reference.
2 Timing & Workflow
- Total time: 150 minutes.
- Suggested pacing: Planning (35–40 min) → PDO/ACE experiments and write-up (75–80 min) → QA table & discussion (30–35 min) → 5 minutes to review data tables, units, and conclusions.
- Equipment: Expect standard titration, calorimetry, or kinetics setups plus reagents for qualitative tests. Calculators and graph paper (or grid space) provided; the data booklet applies to written papers (Papers 1–3), not Paper 4.
