Best OCR A Chemistry books

OCR A has an unusually strong main textbook. Add a write-in workbook and a dedicated calculations book, then use the real exam papers once each topic is secure.

A-Level Chemistry: OCR A Year 1 & 2 Exam Practice Workbook

A well-aligned source of frequent topic practice, particularly useful before moving to the harder questions from OCR papers.

My take: This is the sort of book schools often do not provide because students write in it. Use it as the course progresses, not in one heroic weekend before Paper 1.

Use it for

Weekly consolidation
Extra independent question practice
Quick diagnosis of weak topics

How to use it

Buy an unused copy
Keep returning to older topics
Move on to full OCR papers as the course develops

Best calculations bookUse across two years

Calculations in AS/A Level Chemistry

A durable calculations course with enough worked explanation and repetition to make unfamiliar exam problems less alarming.

My take: For OCR A, skip chapter 9, weak-base pH on pages 201–205, S-total on pages 262–265 and the old mass spectrometry material on pages 20–21. Most of the book remains extremely useful.

Use it for

Core quantitative chemistry
Practice at a wide range of starting levels
Preparation for mixed OCR questions

Worth knowing

Some material is old or outside OCR A
Chapter 9 is unnecessary
Past papers remain the final standard

A Level Chemistry for OCR A Student Book

The strongest full-course OCR A reference, with explanations and questions closely shaped around the specification.

My take: This is the main OCR A textbook I would want a student to have access to. ISBN 978-0-19-835197-9. If school provision is weak, it is the first substantial purchase.

A Level Chemistry for OCR A Revision Guide

A compact OCR A companion with explanations and substantial question practice.

My take: This guide earns its place because of the question practice. Use it alongside the main textbook and remain prepared to query an answer when the chemistry says otherwise.

Useful for

Weekly review during the course
A lighter companion to the main textbook
Additional questions in the examiner style

How to use them during the course

During teaching

Understand

Use the main textbook to resolve difficult explanations and complete selected end-of-chapter work.

After each topic

Practise

Complete the workbook and relevant Jim Clark calculations soon after each topic.

Later retrieval

Mix

Return to older questions and begin full OCR papers. Topic confidence can be misleading when every question arrives under a helpful heading.

Is the Ritchie and Gent textbook worth the price?

Yes when the student lacks reliable access through school. It is comprehensive and closely matched to OCR A. It is poor value as a duplicate of a book already available through the college.

Should I buy the revision guide or the full textbook?

The full textbook is the better explanation source. The revision guide is a useful companion because it adds questions and a more compact review route.

Are there errors in Chemistry books?

Yes. Even good books sometimes contain answer or wording errors. Compare doubtful answers with the specification, reliable chemistry and official mark schemes.
