Chemistrythatcounts Shop

Welcome to Chemistry That Counts I’ve taught chemistry for more than 30 years, including 18 years at an international school teaching Pearson Edexcel International GCSE and International A Level. Everything in this shop comes from that classroom experience: knowing which topics come up again and again, where students lose marks, and what actually helps them improve. You’ll find topic resources for teaching and revising each part of the specification, with practice questions and mark schemes.
