About Prichard Guides
Expert GCSE Science & Maths Revision
Why did I write this series? It all started when my daughter was preparing for her GCSE science exams. Like many students, she was using popular revision guides from the big publishers, full of colourful pages and packed with information. But she quickly realised something important: while they had plenty of questions and answers, they didn’t show her how to work things out.
I found myself spending a lot of time sitting with her, explaining the steps behind the answers, essentially doing what the revision books didn’t. That’s when I realised there was a real gap in the market because most guides offered answers, but not methods and without understanding the method, students struggle to improve.
So, I decided to create something better.
I began writing Physics by Example, the first book in the Learn by Example series, to support my daughter’s revision. I began writing in my spare time, usually in a café or in my car whilst waiting for my other daughter whilst she was at hockey practice or playing matches! The aim was simple: show students exactly how to tackle GCSE questions step by step. What started as a tool for one student quickly became something that could help many more.
Now, the series includes revision guides for Physics, Chemistry, Biology, and Foundation Maths. All written with clarity, understanding, and real classroom experience at their heart.
Learn the method. Master the question. Succeed with confidence.
About Tim Prichard
Over 30 Years of Teaching Experience
I’ve been teaching science since 1990, with a career that’s taken me from busy London classrooms to prestigious international schools in Thailand, and high-performing UK secondary schools. I’ve taught all three sciences at GCSE, as well as A-level Physics and Chemistry. Working with students of all abilities, including those who went on to Oxford and Cambridge.
For 18 years, I was Head of Science at a secondary school in Somerset, where I developed and tested the revision materials that would become the Learn by Example series. These guides have helped countless students achieve top grades – including 8s and 9s – by breaking down questions into clear, workable steps.
I now work in the Chemistry Department at the University of Bath, continuing to support science education with the same passion and focus that has driven my teaching career for over three decades.
A proven track record
Tried & Tested by GCSE Students
As a biology teacher who has to teach KS4 physics I use this book to help my planning. The book is informative, has an attractive layout which makes it easy to follow. The worked examples are very detailed and written in a logical and easy to understand way. Very helpful for staff and students alike. I would recommend this book to any science teacher or student studying physics.

Using physics by example helped me prepare for my physics exam. The countless examples allowed me to see the style of questions and how to answer them.
I also liked the space to try the self-testing bit.
