About me ….

Crunch Chemistry is the resource I wish I had had, both as an A level student and when I first started teaching – essentially an online Chemistry tutor where every concept was taught from first principles, where all the maths was properly explained and equations didn’t appear out of the ether, and where I could find lots practice questions (particularly the really tricky A* ones) with worked-through answers and examiner tips.

My name is Sarah Parkes and I’ve been a teacher of A level Chemistry for over 23 years, working in both comprehensive and grammar schools. I’ve worked with students who have found the subject challenging as well as students who have gone on to study Chemistry, Natural Sciences, Medicine and Veterinary Science at universities across the UK, including Oxford, Cambridge, Durham and UCL.

I know what it takes to succeed – how to teach the key concepts (without dumbing them down), the importance of language, all the common misconceptions, exam technique, examiner tips and how to study smart.

Crunch Chemistry will help you to achieve your potential, showing you how to answer questions, explain material and so build your confidence in your ability to succeed – whether you are aiming for a grade C or an A*.

Together, we can do this!
