• Biology — Biology is the most content-dense of the science subjects, and the difference between a vague answer and a precise one usually comes down to terminology — the exact name of a process, structure or stage.
• Chemistry — Chemistry splits into three quite different ways of thinking — physical (calculation-heavy), organic (structure and reaction-heavy) and inorganic (fact-heavy) — and each chapter tends to sit clearly in one of those buckets.
• Maths — Maths chapters build a toolkit you're expected to combine, not use one at a time — a single exam question often pulls in ideas from two or three different chapters at once.
• Physics — Physics builds from first principles — every later chapter leans on the ones before it, which is exactly why a PDF you can flip back through is more useful than scattered notes.
