ICSE Class 10 Biology Syllabus 2026-27: Detailed Topic-wise Syllabus
Updated for the 2027 ICSE exams: CISCE has published the ICSE 2027 regulations and syllabuses. No chapter deletions have been reported for this subject, and more competency-based questions are expected, but check CISCE's 2027 syllabus and prescribed-book list for your subject.
Biology is a term used to denote the study of living organisms. It explains how life exists and develops. ICSE Class 10 syllabus is well designed. It deals from fundamentals to in-depth topics such as cell division, human body, health, environment, and genetics.
Students are instructed in how the human body functions. The brain, heart, kidneys, hormones, and immunity are discussed. Plant and animal reproduction are included. Ecology and pollution are covered, relating biology to practical issues. Diagrams, flowcharts, and application are used to explain things. Practicals are also prioritised to explain theory more effectively.
This course offers the students not only exam preparation but competitive biology streams as well.
Practising past papers is the best way to use this syllabus. Gradehunt’s ICSE Class 10 test series gives you chapter-wise and full-syllabus papers with detailed evaluation, so you know where you lose marks before the board exam.
