About Physical Sciences examination preparation

Grade 12 Physical Sciences combines Physics and Chemistry. Paper 1 covers mechanics, electricity, waves, and optics, while Paper 2 focuses on chemical bonding, organic chemistry, and electrochemistry.

Every available Grade 12 Physical Sciences past paper and memorandum is collected in the Physical Sciences hub at physical-science.freemode.co.za — browse all years, sessions and languages in one place.

How to use this resource for revision

A past examination paper is most useful when it is treated as an active revision exercise. Try the questions yourself before checking the corresponding memorandum. Where you make an error, identify the reason — was it a knowledge gap, a calculation mistake, an interpretation issue, or an examination technique problem?

For stronger examination practice, complete the paper without unnecessary interruptions and keep track of the questions that take the most time. Afterwards, review the memorandum and separate knowledge gaps from mistakes caused by interpretation, calculation, structure, or examination technique.

applying scientific principles

selecting appropriate equations

interpreting scientific information

performing calculations with correct units

explaining scientific reasoning

A practical revision approach

Create a one-page formula sheet and practice deriving units from first principles. The memorandum rewards correct formula identification, proper substitution, and accurate unit handling.
