O Level Pure Chemistry past papers, marked the way the exam marks it.
THE BANK
Every chapter, with real papers behind it
FullMarks holds 2,467 O Level Pure Chemistry questions, 412 of them carrying a full marking scheme, so a written answer can be marked against the same points an examiner would use. The chapters with the most practice behind them:
- Electrochemistry
- Organic Chemistry
- Atoms, Molecules and Stoichiometry
- Chemical Bonding
- Chemical Periodicity
- Practical Chemistry
- Metals
- Chemical Energetics
- Acids, Bases and Salts
- Qualitative Analysis
- Reaction Kinetics
- Atomic Structure
- Kinetic Particle Theory
- Ionic Equilibria
- Polymerisation
- Hydrocarbons
- Chemical Equilibria
- Air and Environment
HOW MARKING WORKS
Where the marks actually go
Chemistry marks sit on precision. The mark is not for knowing that a reaction happens, it is for naming the species, the bond, or the intermolecular force involved, and for saying which one is stronger and why. An answer that says "hydrogen bonding" when the scheme wants "hydrogen bonding between the hydroxyl group and water" is describing the right chemistry and still missing the point that is being paid for.
Handwriting-quality English is not what is being marked. An answer written in short, ungrammatical fragments can score full marks if every required statement is present. But naming the keywords is not enough either. Where the scheme asks you to connect two ideas, listing both without joining them earns nothing for that point. Padding an answer with extra terms in the hope that one of them lands does not work, and can cost you marks a shorter answer would have won.
WHAT YOU GET
Write it as you would in the paper
You practise real O Level chemistry questions and answer them the way you will on the day. Type them, photograph your handwritten working, or draw straight onto the screen. It comes back marked immediately, point by point. Where you lose a mark you are told exactly what was missing, rather than being shown a model answer and left to spot the difference yourself. If an explanation does not land, you can ask for the same thing again in plain words.
