ISI Test Syllabus 2026: An Overview for Engineering Aspirants

- 5 min read
The ISI Admission Test is not your typical entrance exam. Unlike others that might reward rote memorization or speed-drills, ISI evaluates your "mathematical maturity"—the ability to think from first principles and solve non-routine problems. For 2026, the institute continues to emphasize foundational logic alongside advanced computational theories.
The Prestige and the "ISI Advantage"
Why do thousands of engineering students pivot toward ISI? It comes down to two factors: Research Excellence and Unmatched ROI. With a zero-tuition fee structure and substantial monthly stipends for all students (approx. ₹5,000 for UG and ₹12,400 for M.Tech), the return on investment is virtually infinite. Graduates from ISI are the first choice for global tech giants like Google, Microsoft, and quantitative finance firms.
Detailed Breakdown of the ISI Test Syllabus 2026
The syllabus is categorized based on the program you are applying for. For 2026, the core mathematical foundations remain the same, but there is an increased focus on discrete structures and algorithmic logic in the M.Tech (CS) papers.
1. Undergraduate Programs: B.Stat (Hons) and B.Math (Hons)
The undergraduate syllabus is divided into two parts: UGA (Multiple Choice) and UGB (Descriptive). The ISI Test Syllabus 2026 for these programs covers:
Algebra: Sets, operations on sets, prime numbers, factorization of integers, divisibility, rational and irrational numbers, permutations and combinations, Binomial Theorem, logarithms, and complex numbers.
Theory of Equations: Remainder Theorem, quadratic equations, relations between roots and coefficients, and symmetric functions of roots.
Calculus: Limits, continuity, derivatives, tangents and normals, maxima and minima, and methods of integration (definite and indefinite).
Geometry & Trigonometry: Plane geometry, coordinate geometry (lines, circles, conics), and trigonometric identities/equations.
Number Theory: Elementary number theory, congruences, and the Pigeon-hole Principle (a favorite for UGB).
2. Postgraduate Programs: M.Tech (Computer Science)
For engineering graduates, the M.Tech (CS) entrance is the primary gateway. The syllabus is split into Mathematics (MMA) and Computer Science (PCB).
Mathematics (MMA) Section:
Linear Algebra: Vector spaces, matrices, rank, trace, eigenvalues, and eigenvectors.
Probability: Random variables, distributions (Binomial, Poisson, Normal), and expectations.
Discrete Mathematics: Graphs, trees, and combinatorics.
Computer Science (PCB) Section:
Data Structures & Algorithms: Arrays, stacks, queues, linked lists, binary trees, sorting, and searching.
Programming: Mastery of C, C++, or Python is essential.
Operating Systems: Process management, memory management, and deadlocks.
Formal Languages: Automata theory and Turing machines.
Exam Pattern and Marking Scheme for 2026
Understanding the architecture of the paper is as important as the syllabus itself. The ISI 2026 exam will follow an offline (Pen & Paper) format.
Feature | B.Stat / B.Math (UG) | M.Tech (CS) |
Session 1 (Forenoon) | 30 MCQs (UGA) | 30 MCQs (MMA) |
Session 2 (Afternoon) | Subjective (UGB) | Subjective (PCB) |
Total Marks | 100 + 100 | 100 + 100 |
Negative Marking | -1 for MCQs (Check specific rules) | -1 for MCQs |
Stipend Offered | ₹5,000/month | ₹12,400/month |
Strategic Note: In the MCQ section, ISI often employs a unique marking scheme where "Not Attempting" a question might earn you +1 mark, whereas a "Wrong Answer" gives 0. This makes the ISI Test Syllabus 2026 preparation more about accuracy than volume.
Important Tentative Dates for ISI 2026
Aspiring candidates should mark their calendars for these key milestones in the 2026 admission cycle:
Notification Release: Late January 2026
Application Window: March 1 – March 31, 2026
Admit Card Download: Mid-April 2026
ISI Admission Test 2026 Date: Second Sunday of May 2026 (Tentative)
Result Declaration: June 2026
Interview Rounds: July 2026
Preparation Strategy: Cracking the 2026 Exam
To master the ISI Test Syllabus 2026, you must transition from a "solver" to a "thinker."
Build a Foundation with "TOMATO": The book Test of Mathematics at the 10+2 Level (published by ISI) is the bible for aspirants. Solve it cover to cover twice.
Master Descriptive Writing: Unlike JEE, the UGB and PCB papers require you to write rigorous proofs. Practice explaining "Why" a step is taken, not just "What" the result is.
Focus on Combinatorics & Number Theory: These are the high-weightage "gatekeeper" topics. If you can solve a complex Pigeon-hole Principle or Modular Arithmetic problem, you are ahead of 90% of the applicants.
Engineering ROI Analysis: For M.Tech aspirants, focus on the "Computer Science" fundamentals. The ROI of an ISI M.Tech is unparalleled because the stipend covers your living costs, and the placement packages for 2025/26 are projected to average ₹25–30 LPA.

Data Science: Leading data-driven decision-making in Fortune 500 companies.
Government Sector: Shaping national policy through the Indian Statistical Service (ISS).
Frequently Asked Questions (FAQs)
1. What is the main focus of the ISI Test Syllabus 2026?
The primary focus of the ISI Test Syllabus 2026 is to evaluate a candidate's depth in logical reasoning and conceptual mathematics. It emphasizes topics like Calculus, Combinatorics, Number Theory, and Linear Algebra, moving away from repetitive formula-based questions.
2. Can engineering students apply for ISI M.Tech without a GATE score?
Yes, engineering students (B.E./B.Tech) can apply through the ISI Admission Test. However, those with high GATE scores in Computer Science or Mathematics may be eligible for direct interviews, bypassing the written test.
3. Is the ISI syllabus different for B.Stat and B.Math?
The entrance syllabus for B.Stat and B.Math is identical. The differentiation only happens during the degree program, where B.Stat focuses more on Applied Statistics and B.Math on Pure Mathematics.
4. How difficult is the subjective part of the ISI exam?
The subjective paper (UGB/PCB) is generally considered very difficult because it requires rigorous proof-writing. You must demonstrate a clear logical flow to earn full marks.
5. What is the stipend for M.Tech CS students at ISI?
The expected stipend for M.Tech CS students during the 2026-28 batch is approximately ₹12,400 per month, provided the student maintains a minimum academic performance.
