AQA GCSE Combined Science Chemistry mock draft, 26–31 Oct. Draft coverage: Combined Science Chemistry Paper 1 (Higher tier). Reviewed for an original-practice sitting; check student availability before registering. Marking and results will follow later, after separate approval. Eligible new accounts receive a five-day Pro trial when signup email verification completes. Previous trials keep their original expiry. After expiry, new papers need Pro unless you have an explicitly confirmed free sitting offer for this event. That offer adds no Pro time or AI learning. Saved attempts and released results remain readable. No card or automatic charge.

An alloy is a mixture of two or more elements, at least one of which is a metal. The Layered Structures and Alloys notes cover this in full.
A polymer is a substance with very large molecules made from many repeating units, called monomers, joined by strong covalent bonds. The Structure and Properties of Polymers notes cover this in full.
Graphite has a layered giant covalent structure in which each carbon atom forms three covalent bonds with neighbouring carbon atoms, creating hexagonal rings. The Structure and Properties of Graphite notes cover this in full.
A covalent bond is a chemical bond formed when two atoms share a pair of electrons. The Understanding covalent bonds and drawing molecules notes cover this in full.
Ionic bonding is the electrostatic attraction between oppositely charged ions formed when electrons are transferred from metal atoms to non-metal atoms. The Understanding Ionic Structure and Bonding notes cover this in full.
The changes of state are melting (solid to liquid), freezing (liquid to solid), boiling (liquid to gas) and condensing (gas to liquid). The States of Matter and Particle Theory notes cover this in full.
A monomer is a small molecule that acts as a single repeating unit of a polymer. The Structure and Properties of Polymers notes cover this in full.
Metallic bonding is the electrostatic attraction between positive metal ions and a sea of delocalised electrons that can move freely throughout the structure. The Giant Metallic Structure and Bonding notes cover this in full.
