QCE Physics EA Practice Units 3 & 4
Practice questions on gravity and motion, electromagnetism, special relativity, quantum theory and the Standard Model.
QCE Physics Units 3 and 4 cover gravity and motion, electromagnetism, special relativity, quantum theory, and the Standard Model of particle physics. The EA contributes 50% of your subject result and emphasises problem-solving, mathematical modelling, and explaining physical phenomena. Revizi’s practice questions target the calculation types and conceptual questions typical of the QCAA external assessment.
External Assessment: External assessments (EAs) are centrally set examinations developed by QCAA for each General subject. For Physics and the other science subjects, the EA contributes 50% of the overall subject result (IA1 10% + IA2 20% + IA3 20% = 50% internal, 50% external). The EA tests problem-solving with calculations, conceptual understanding, and data analysis across Units 3 and 4.
