Grade 12 Term 3 test, paper set 2, in the format of the G.C.E. (A/L) Physics Paper I: 50 multiple-choice questions, two hours, g = 10 N kg⁻¹, speed of sound in air 340 m s⁻¹ unless stated, no calculators. About 60% of the marks are on this term (the Doppler effect and sound intensity, refraction, total internal reflection and prisms, lenses and the eye, and thermal physics: thermal expansion, gases and kinetic theory, heat capacity and latent heat, vapours and humidity, the first law of thermodynamics and heat transfer) and about 40% on Terms 1 and 2 (measurement, mechanics, oscillations and waves).
