Every NSC past paper question, sorted by CAPS topic and linked to its memo. Pick a topic and practise only that, without paging through whole papers.
Every paper has a graph to interpret. Each guide rearranges the equation into a straight line so the slope and intercept mean something.
Grade 11 and 12. All six graphs, each built from ε = I(R + r).
Grade 12. All eight graphs, and what the gradient and each intercept tell you.
Grade 12. Rate, concentration and moles against time, and how each disturbance shows up under Le Chatelier's principle.
One question at a time until only one answer is left.
Grade 11. Start with one question, is there a battery? Follow it to Faraday's law, Lenz's law or the right-hand rule.
Three chemistry guides that follow on from each other. Read them in this order.
Grade 11. Covalent, ionic and metallic bonding, electronegativity differences, bond energy and Lewis structures.
Arrhenius and Lowry-Brønsted theory, strong and weak acids, indicators and titration stoichiometry.
Ka, Kb and Kw, pH calculations, conjugate pairs, hydrolysis and titration curves.
