3. Syllabus & Exam Pattern
The entrance exam is 3 hours long, conducted online, and held in English.
A. Computer Science & Systems Science (LIDS)
Focuses heavily on mathematical aptitude and theoretical CS foundations:
- Discrete Mathematics: Sets, relations, graph theory, propositional logic, and probability.
- Algorithms & Data Structures: Complexity (Big O), sorting/searching, trees, and NP-completeness.
- Core CS: Operating systems, database theory, formal languages/automata, and digital circuits.
- Systems Science (LIDS): Calculus, Linear Algebra, and Signal Processing.
B. Physics
Tests conceptual depth at the undergraduate and introductory master’s levels:
- Pattern: ~40 MCQs split into Section A (Basic) and Section B (Advanced).
- Core Areas: Classical Mechanics, Quantum Mechanics, Electricity & Magnetism, Thermodynamics/Statistical Physics, and Modern Physics.
C. Mathematics
- Pattern: Part A (Multiple Choice Questions) and Part B (True/False statements). Candidates applying for specific research centers (e.g., TIFR-CAM) are primarily evaluated on Part A.
- Core Areas: Real Analysis, Linear Algebra, Abstract Algebra, and Geometry/Topology.
