ISC Maths Tutors for Class 11 & 12

ISC maths at a glance

ISC is the Indian School Certificate, the Class 12 examination run by the Council for the Indian School Certificate Examinations (CISCE). The maths subject most science students take is Mathematics, subject code 860. CISCE describes it as the course for students heading towards mathematics, physics, chemistry, engineering, architecture and related fields.

The shape is the same in both years. Each year has a three-hour theory paper worth 80 marks and project work worth 20 marks. The difference is who sets the paper: the Class 11 final examination is conducted by the school, while the Class 12 paper is the ISC board examination set by CISCE.

There is a second maths subject in ISC, Applied Mathematics (subject code 885), meant for students heading towards commerce, economics, humanities, biosciences and the social sciences. A student cannot take both. Most of this guide is about Mathematics (860), because that is what "ISC maths" usually means; Applied Mathematics comes up again in the section on Sections B and C.

ISC Class 11 maths: the syllabus and marks

Class 11 is where ISC maths gets serious. The CISCE syllabus for Class 11 spreads the 80 theory marks across five units:

Algebra and coordinate geometry carry more than half the marks, and both are heavy. Trigonometry arrives with a long list of identities, conics bring a new kind of geometry, and permutations and combinations reward careful thinking more than formula recall. Calculus is only 8 marks in Class 11, but limits and derivatives are the base for the 35 marks of calculus in Class 12.

Because the Class 11 examination is set by the school, papers vary in length and difficulty from school to school. Some schools set papers close to the board standard; others are gentler. Either way, the Class 11 syllabus is the foundation for Class 12 and for JEE, so a student who coasts through it tends to pay for it the following year. Our Class 11 maths tutor page covers this year across boards.

ISC Class 12 maths for the 2027 exam: the syllabus and marks

For students sitting the ISC examination in 2027 (in Class 12 during 2026-27), CISCE's syllabus lists seven units, all compulsory. The 2028 syllabus, published in January 2026, keeps the same units and marks:

Calculus is almost half the theory paper, and it is where the year is won or lost. The syllabus notes a few boundaries worth knowing: equations reducible to variable-separable form are included in differential equations, second-order differential equations are excluded, and proofs of geometrical theorems using vectors are excluded. A tutor who knows these edges saves the student time on material that will not be examined.

Syllabuses are revised from time to time, and CISCE's rule is that candidates follow the syllabus of the year in which they sit the examination. Always check the current CISCE syllabus for your child's exam year before relying on any table, including this one.

ISC maths Section B and Section C: what changed

Many families still search for help with "ISC maths Section B or C", and many guides, textbooks and older papers are built around it, so it is worth being clear about what has changed.

Up to the 2026 examination, the Class 12 paper had a compulsory Section A worth 65 marks and then a choice: students answered all the questions from either Section B or Section C, each worth 15 marks. Under the revised 2026 syllabus, Section B covered vectors, three-dimensional geometry and applications of integrals, while Section C covered applications of calculus in commerce and economics, linear regression and linear programming. Schools usually decided which section they taught, broadly Section B for engineering-minded students and Section C for commerce students.

From the 2027 examination, the CISCE syllabus for Mathematics (860) no longer divides the paper into Sections B and C. Vectors, three-dimensional geometry and linear programming are now compulsory units for every student, area under curves sits inside calculus, and linear regression no longer appears in the Mathematics syllabus. Students who want a maths course aimed at commerce and economics now have Applied Mathematics (885), whose Class 12 syllabus includes financial mathematics, index numbers and moving averages.

What this means in practice:

• Old papers need care. ISC maths papers up to 2026 contain Section C questions on regression and commerce applications that are no longer in the 860 syllabus. They are still excellent practice for Section A, but a tutor should flag which questions to skip.
• Commerce students with Mathematics (860) must now do vectors and 3D geometry. For a student who expected Section C, that is roughly eleven marks of unfamiliar geometry. It is very learnable, but it needs to be planned.
• The subject choice matters more than before. In Class 11, families choosing between Mathematics and Applied Mathematics are really choosing the course, not a section. Engineering, architecture, physics and JEE point to Mathematics (860); many commerce, economics and humanities routes are served by Applied Mathematics, but check the entry requirements of the specific degree courses your child is considering.
• Repeaters follow the new syllabus. A student taking the examination again follows the syllabus for the year of that examination, not the one they studied.

CISCE had not yet published a 2027 specimen paper for Mathematics when this guide was written. The specimen paper shows how many questions there are and where the internal choices sit, so look for it on cisce.org and practise with it as soon as it appears.

How the ISC Class 12 maths paper works

The detailed layout for 2027 will be confirmed by the specimen paper, but several features of ISC maths papers have been stable and are worth building habits around. Going by the CISCE specimen paper for 2026:

• Fifteen minutes of reading time. Students may read but not write. It is the time to choose between internal-choice questions and to spot the questions to do first.
• A mix of question lengths. The paper opens with short items, including multiple-choice questions where only one option is written as the answer, and builds to longer questions worth several marks each.
• Internal choices. Some questions offer an either/or. Choosing quickly and sticking with the choice saves more time than students expect.
• Working on the same page. All working, including rough work, must be done on the same page as, and next to, the rest of the answer. Examiners look at it.
• Tables and graph paper are provided. Students should not bring their own.

On calculators, the current ISC regulations permit the Casio fx-82 MS scientific calculator, calculators of other makes with similar functions, or basic calculators; any calculator that can store and retrieve information is not allowed. That does not mean every step can be handed to the calculator. ISC maths marks come from method, so the student still needs to show the working. Check the regulations for your exam year and any instructions printed on the paper.

The ISC maths project: 20 marks worth taking seriously

Project work is Paper II, and it is worth 20 marks in each of Classes 11 and 12. That is a fifth of the subject, and unlike the theory paper, much of it can be secured before the examination season begins.

Each student completes two projects, each marked out of 10. The syllabus sets out how the marks are divided:

CISCE provides a list of suggested project topics. In Class 12 these include finding areas bounded by pairs of curves, comparing methods for finding the area under a curve, tessellations and the derivation of determinants. Class 11 suggestions include illustrating trigonometric graphs, constructing conics and using Pascal's triangle for binomial expansions. No question paper is set for the project.

The part students underestimate is the viva. Three marks per project depend on the student explaining their own work to the Visiting Examiner. A project that was heavily "helped" at home shows up quickly in a viva. The right role for a tutor is to help the student choose a topic they can handle, check the mathematics, push for clear findings and rehearse the viva questions, while the work itself stays the student's.

How ISC maths differs from CBSE Class 12 maths

With Sections B and C gone, ISC Class 12 maths now looks closer to CBSE than it used to. The topic lists overlap heavily and calculus carries 35 of the 80 theory marks on both boards. The differences that remain are real, though, and they change how a student should prepare:

The textbook point matters more than it looks. A CBSE student can treat NCERT as the course. An ISC student cannot treat any single book that way; the CISCE syllabus is the real guide, and schools use different books. A good ISC tutor works from the syllabus and the student's school book together.

Class 11 is where the boards differ most. The ISC Class 11 syllabus is dense, and ISC students often meet topics in more depth or a different order from CBSE students. For the CBSE side of the comparison, including the CBSE unit weightage and question paper design, see our Class 12 maths tutor page.

The jump from ICSE Class 10 to ISC Class 11

Students arriving from ICSE Class 10 usually have two big strengths: they are used to writing full working, and they are used to long papers. Those habits carry straight into ISC. What catches them out is the change in the mathematics itself.

The months after Class 10 boards are the easiest time to prepare. A few weeks on algebraic fluency, the basics of functions and early trigonometry make the first term of Class 11 far easier. Families still in ICSE Class 10 in Gurugram can see our ICSE maths tutor in Gurgaon page; the same advice applies anywhere.

Some students join ISC from CBSE, IGCSE or IB schools. They face the same jump, plus the ISC style of setting out working. A tutor who has taught those courses can map the gaps quickly; see our IGCSE maths tutor and IB maths tutor pages for those courses.

ISC maths and JEE

Many ISC science students also prepare for JEE, and the overlap is large. Most of what the ISC syllabus covers also appears in JEE Main maths: in Class 11, complex numbers, quadratic equations, permutations and combinations, the binomial theorem, sequences and series, straight lines, circles and conics; in Class 12, functions, matrices and determinants, calculus, vectors, three-dimensional geometry and probability.

The change for 2027 helps JEE students. Vectors and three-dimensional geometry are now compulsory in ISC, so no ISC science student skips them because their school chose the other section.

The difference is in the style of question. ISC rewards complete, well-presented working on questions that are usually direct applications of the syllabus. JEE rewards speed and the ability to combine ideas from several chapters, with no credit for working. A student preparing for both needs:

• One set of concepts, two kinds of practice. Learn each chapter once, properly, then practise it both ways: written, board-style solutions, and timed objective problems.
• Protected board time. In Class 12, the months before the ISC examination should be about ISC papers and presentation, even for committed JEE students. Board marks matter for many admissions.
• A tutor who is honest about the difference. An ISC tutor is not automatically a JEE coach, and the reverse is also true. Say which you need, or whether you need both.

JEE planning usually involves physics and chemistry too; our JEE physics tutor page explains how we approach entrance preparation alongside the boards. Always check the current JEE syllabus published by the conducting body, since it changes independently of ISC.

A term-by-term plan for ISC Classes 11 and 12

Schools order chapters differently, so a tutor follows the school's sequence and fills in around it. This is the shape that works for most ISC maths students:

Two things tend to go wrong. Class 11 is treated as a light year, and the calculus foundation is missing when Class 12 starts. And the projects are left to the last fortnight, when they compete with pre-board revision. Both are easy to prevent if the plan is made in April rather than December.

Students who start with a tutor late in Class 12 can still improve a great deal. The usual order is to secure calculus first, because it carries the most marks, then the shorter units that reward direct practice, such as matrices, linear programming and probability.

Working and presentation: where ISC marks are kept

ISC maths gives marks for method. A correct final answer with no working can lose most of the marks for a question, and a wrong answer with sound working can keep many of them. When I review an ISC student's written work, these are the habits I look for first:

Rough work belongs next to the answer, not on a separate sheet. None of this is complicated, but it only becomes automatic if someone reads every line the student writes, every week, and corrects the layout as well as the mathematics.

How to choose an ISC maths tutor

A strong general maths tutor is not automatically a good ISC maths tutor. These are the questions worth asking before and during the demo class:

• Do they teach ISC now? The 2027 changes mean a tutor working from memory of the old Section B and C paper can plan the year wrongly. Ask how they are handling the new syllabus.
• Do they work from the CISCE syllabus? Since there is no single ISC textbook, a good tutor knows the syllabus boundaries and works around the student's school book.
• Do they mark working, not just answers? In the demo, watch whether the tutor reads the student's written steps and corrects the setting out.
• Can they support the projects properly? Helping a student choose a topic and prepare for the viva is valuable; doing the project for them is not.
• Are they clear about JEE? If your child is preparing for JEE, ask whether the tutor covers both, and how they would balance the two.
• Does the student understand them? The most useful check of all. After the demo, ask your child whether the explanation made sense and whether they would be comfortable asking a question they felt silly about.

For students in lower classes or on other boards, our maths home tutor page covers maths tuition more broadly.

Home or online ISC maths tuition, anywhere in India

ISC schools are spread across India, with large numbers of ISC students in cities such as Kolkata, Lucknow, Delhi NCR, Mumbai, Bengaluru and Dehradun, and in many smaller towns. Experienced ISC maths tutors are not evenly spread, which is why families choose between home and online tuition differently depending on where they live.

Whichever you choose, the essentials are the same: the tutor knows the current ISC syllabus, sees the student's written working and sets work between sessions.

Fees and getting started

Across NXTutors, most home-tuition sessions fall between ₹800 and ₹2,500 an hour; Classes 11–12, IB/IGCSE and JEE/NEET sit toward the upper end; specialists for IB HL or JEE Advanced can charge more. ISC maths, especially Class 12 board preparation, generally sits in the upper part of that range. The fee also depends on the tutor's experience, whether sessions are at home or online, travel time and how many sessions a week you take. You see each tutor's fee before the demo, and our pricing guide explains more.

Two sessions a week is typical through most of Classes 11 and 12, rising to three from the pre-boards. A student who is already secure may need only one, focused on papers and presentation.
