Heaviest topic: Coordination and Response, 326 marks across 119 questions.
Across every 0610 paper in these banks, the three heaviest topics are Coordination and Response (326 marks), Reproduction (296 marks) and Human Nutrition (286 marks). The first of those alone is about 9% of every mark on offer. The lightest is Drugs at 32 marks.
That matters because revising by whole past paper spreads your time evenly over topics the examiner does not weight evenly. Working topic by topic lets you spend the most time where the most marks are, and it shows you the handful of question shapes each topic actually uses rather than meeting one of them every few weeks.
Past papers are easiest to use when the questions are already sorted by topic, so you can finish one topic before starting the next instead of meeting it once every few papers. ExamYard prints the real Cambridge questions for IGCSE Biology 0610 arranged that way, with the mark scheme kept separate from the question. Chapter 1 of every book is free to read, with no account and no email address.
