Both specifications are part of the OCR A-Level Chemistry syllabus, but they are slightly different in content structure and assessment style.
Chemistry A (H432) focuses on traditional content with a linear assessment model. It includes modules like foundations of chemistry, periodic table, and organic chemistry.
Chemistry B (H433) (Salters’ approach) takes a context-led route with real-life applications of chemistry in areas such as pharmaceuticals and green chemistry.
Whichever one you are taking, we’ve got you covered with the latest and complete collection of OCR A-Level Chemistry A (H432) & B (H433) Past Papers at Exam Papers Practice.
How to Use Past Papers to Achieve an A*
1. Start Early and Practice Regularly
Don’t wait until a month before your exam to start using past papers. Begin early in the school year and aim to complete at least one paper every two weeks. As your exam date approaches, increase the frequency.
🧠 Tip: Create a revision schedule that includes “Past Paper Fridays” to get into the habit.
2. Use Mark Schemes Wisely
Each past paper comes with an official mark scheme, available on Exam Papers Practice. Use it after completing your paper to mark your work and understand how points are awarded.
Look for keywords and specific terms that examiners want. This can turn a B answer into an A* one.
📘 Tip: Highlight recurring command words like describe, explain, calculate, and make flashcards with their expectations.
3. Identify Weak Topics
After completing 2–3 papers, look back and note which topics you repeatedly struggle with. Is it redox reactions, enthalpy changes, or reaction mechanisms?
Focus your revision on these areas before moving on to more past papers.
📈 Tip: Keep a “Mistake Tracker” to log every question you get wrong — and revisit them weekly.
4. Time Yourself
In the actual exam, time is your biggest enemy. Practice under timed conditions to train your brain to think fast and write clearly.
The OCR A-Level Chemistry A (H432) & B (H433) papers usually include:
Paper 1: 2 hours 15 minutes
Paper 2: 2 hours 15 minutes
Paper 3: 1 hour 30 minutes (for practical skills and synoptic understanding)
⏱️ Tip: Try using a Pomodoro-style timer — 25 minutes of focus, 5 minutes break — for effective exam simulation.
5. Understand the Examiner’s Language
When you review the mark schemes and examiner reports (also available on Exam Papers Practice), pay close attention to how answers are phrased.
Understanding how OCR wants students to phrase and structure answers can boost your marks.
📌 Tip: Practice writing one-mark answers using bullet points and longer ones using PEEL (Point, Evidence, Explain, Link).
