Amount of substance hub
Overview page summarises every strand so students can dive straight into the area they need, whether it is gas volumes or ionic equations.
A level app
A Level Mole Calculations
A comprehensive, ad-free workspace for post-16 learners who need to push mole concepts beyond GCSE foundations and into exam mastery.
Designed with UK A level specifications in mind, the app surfaces targeted practice for each topic, blends teaching with assessment, and keeps every screen clear so students can concentrate on the chemistry.
Advanced question sets with clean mark schemes and tracking.
Built for depth
Everything you need for post-16 amount of substance
Dynamic question generation creates endless variations, keeping revision purposeful across equilibrium stoichiometry, titration data, and multi-step reasoning.
Practice mode provides guided walkthroughs, mark schemes, and a favourites list so complex worked examples are never more than a tap away.
Quiz, mini review, and mixed-topic tests help students prove mastery under timed conditions while dashboards capture progress lesson by lesson.
