ICSE Class 10 Syllabus: Groups, Marks and Chapter Lists

School boards80 plus 20 marks33% to passUpdated 26 Oct 2026

The ICSE class 10 syllabus is set by CISCE and is arranged in three groups: compulsory subjects (English, a second language, and History, Civics and Geography), a choice of two or more from Group II such as maths and science, and one applied subject from Group III such as Computer Applications. Group I and II subjects carry 80 marks in the board paper and 20 for internal assessment, while Group III subjects split their marks evenly between the paper and school work.

Below you will find how subjects are chosen, the marks and length of each paper, the chapter lists for the main subjects, and a revision plan for the months before the board exam. If you are weighing boards, set it beside the CBSE class 10 syllabus.

You need 33% in a subject to pass it. English must be passed, and your overall percentage is usually worked out from English plus your four best other subjects. Maths and science papers have a compulsory Section A of short and objective items worth 40 marks, then a Section B where you answer four longer questions out of a larger set.

Mathematics chapters

  • Commercial maths: GST, banking (recurring deposit accounts), shares and dividends.
  • Algebra: linear inequations, quadratic equations in one variable, ratio and proportion, factorisation using the remainder and factor theorems, matrices, arithmetic and geometric progressions.
  • Coordinate geometry: reflection, section and mid-point formula, equation of a straight line.
  • Geometry: similarity, loci, circles and tangents, constructions.
  • Mensuration: cylinder, cone and sphere, including combined solids.
  • Trigonometry: identities, use of tables, heights and distances.
  • Statistics and probability: mean, median, quartiles and mode, histograms and ogives, simple probability.

Physics, chemistry and biology chapters

Physics

  • Force, work, power and energy, and simple machines
  • Refraction at plane surfaces, lenses and the spectrum
  • Sound: natural and forced vibrations, echoes, loudness, pitch and quality
  • Current electricity, household circuits and electromagnetism
  • Calorimetry and specific and latent heat
  • Radioactivity and nuclear energy

Chemistry

  • Periodic properties and their variation
  • Chemical bonding: electrovalent, covalent and coordinate
  • Acids, bases and salts; analytical chemistry
  • Mole concept and stoichiometry
  • Electrolysis and metallurgy, including extraction of aluminium and alloys
  • Study of hydrogen chloride, ammonia, nitric acid and sulphuric acid
  • Organic chemistry: homologous series, isomerism, naming, hydrocarbons

Biology

  • Cell cycle, cell division and the basics of genetics
  • Plant physiology: absorption by roots, transpiration, photosynthesis, plant hormones
  • Human systems: circulatory, excretory, nervous with sense organs, endocrine and reproductive
  • Population and its control, and pollution

History, Civics, Geography and Computer Applications

History and Civics

  • Civics: the Union Parliament, the President and Vice President, the Union Cabinet led by the Prime Minister, the Supreme Court, High Courts and subordinate courts.
  • History: the revolt of 1857, the rise of nationalism, early nationalists and assertive nationalists, the Gandhian movements, the Muslim League, Subhas Chandra Bose and the INA, independence and partition, the two World Wars, the rise of dictatorships, the United Nations and the Non-Aligned Movement.

Geography

  • Toposheet reading and the map of India
  • Climate, soils, natural vegetation and water resources
  • Minerals and energy, agriculture, industries, transport and waste management

Computer Applications

  • Java basics revisited, classes and objects, user defined methods, constructors
  • Library classes and wrapper classes, encapsulation
  • Arrays with searching and sorting, string handling

What usually needs the most time

Any honest syllabus of ICSE class 10 rewards some subjects for daily effort more than others. Maths carries a long paper with step marks, so steady daily practice pays more than last minute reading. In science, numericals in physics (lenses, electricity, calorimetry) and equations in chemistry usually separate an 85 from a 95. History needs answers written in the board's point by point style, and geography loses easy marks if you skip the toposheet question practice.

Ananya is in class 10 in Pune and finds geography toposheets confusing. Her teacher suggests one toposheet every Sunday for ten weeks, marking contours, settlements and grid references. By the preboard, the toposheet question becomes her surest section.

A revision plan for the board months

  1. July to September: finish chapters in school order, and work through each exercise within a week of the lesson.
  2. October and November: complete internal projects early so they do not eat into revision, and start one past paper a week per subject.
  3. December and January: full timed papers, two hours for most subjects and two and a half for maths, then check against the marking scheme.
  4. Last three weeks: formula sheets, chemical equations, dates in history and the map list.

The class 10th ICSE syllabus and specimen papers go together, so ask your school for the specimen papers CISCE releases, because they show the current question style.

Getting the ICSE 10th syllabus from CISCE

Many students search for the CISCE org syllabus class 10 documents, and that is the right place to go: the regulations and subject syllabuses for the ICSE class 10 exam are posted on cisce.org, along with specimen papers. Your school also shares the session plan. If you move to class 11 in the same board, the next step is the ISC class 12 syllabus. Other boards, including the open schooling route in the NIOS class 10 syllabus, are compared on the school boards page.

Chapter lists here follow the latest CISCE syllabus as reported. The council can add or drop topics for a session, so match this list with the official document for your exam year.

Frequently asked questions

How many subjects are there in ICSE class 10?

You take at least six: the three compulsory Group I subjects, two or three from Group II and one from Group III. History, Civics and Geography counts as one subject with two papers.

What score clears an ICSE class 10 subject?

You need 33% in each subject, with theory and internal marks added together. English is compulsory to pass.

Is science one paper or three in ICSE?

Three. Physics, Chemistry and Biology are separate 80 mark papers of two hours each, and each has 20 internal marks.

How is the ICSE percentage calculated?

It is usually taken from English plus your best four other subjects. Schools and colleges may set their own rule, so check what your next admission asks for.

Where is the official class 10 ICSE syllabus posted?

From the regulations and syllabus section of the CISCE website. Your school also receives the syllabus at the start of each session.

Is the ICSE syllabus harder than CBSE?

ICSE covers more detail in English and has longer subject lists, while CBSE follows NCERT books closely. Neither is easy, and the right choice depends on how you like to study.
