The Prelim is the full-dress rehearsal for the O-Level paper: the whole Combined Science (Physics) syllabus in one sitting. Waves and light from the start of Sec 4, plus the electricity block, practical electricity, magnetism and radioactivity — the later chapters usually carry the most marks.
Set out like a school paper, with a separate mark scheme for checking.
