Start with Criteria-based learning to see how criteria A–D are assessed, then work through the topic chapters. Each chapter tags its objectives to the criteria, teaches the chemistry with interactive models, and ends with examination practice, the examiner’s overall observation and a knowledge organiser.

Criteria-based learning
Know what each criterion rewards. Plan, process and argue the way the marks are awarded.
- Topic 1
Periodic table
Position predicts behaviour. Read the group, the period and the block, and the chemistry follows.
- Topic 2
IUPAC naming and classification
A systematic name is a set of instructions. Read the stem for the chain, the ending for the family, and the number for the position.
- Topic 3
The atmosphere
Air is a mixture you cannot see. Know what is in it, how to test for it, how we take gases out of it, and what we put back in.
- Topic 4
Matter
Everything is made of particles in constant motion. Their arrangement explains the states; their structure explains the elements.
- Topic 5
Pure and impure substances
Almost nothing around you is pure. Know the kinds of mixture, and choose the separation that exploits the property the components do not share.
- Topic 6
Bonding
How atoms hold together decides how substances behave. Count the atoms, count the moles, and follow the energy and the collisions.
- Topic 7
Types of chemical reaction
Most reactions are either a hand-over of protons or a hand-over of electrons. Learn to see which, and the products follow.
