Exam pattern¶
| Section | Questions | Marks |
|---|---|---|
| General Aptitude (common to all papers) | 10 | 15 |
| Subject: paper-specific Engineering Mathematics (about 13 marks) + Electronics and Communication | 55 | 85 |
| Total | 65 | 100 |
- Question types: MCQ (one correct), MSQ (one or more correct, no partial credit), NAT (numerical). Questions carry 1 or 2 marks.
- Negative marking for MCQ only: −1/3 (1-mark) and −2/3 (2-mark). MSQ and NAT have none.
- 3 hours, computer-based, in English; virtual scientific calculator on screen only (physical calculators banned).
Syllabus¶
Sections (a topic summary; the official syllabus PDF is the authority):
- Engineering Mathematics: linear algebra, calculus, differential equations, vector analysis, complex analysis, probability and statistics.
- Networks, Signals and Systems: circuit analysis, two-port networks, LTI systems, Fourier/Laplace/z transforms, sampling.
- Electronic Devices: semiconductor physics, junctions, BJT, MOSFET, device fabrication basics.
- Analog Circuits: diode circuits, amplifiers, op-amps, oscillators, filters.
- Digital Circuits: number systems, combinational and sequential logic, data converters, memories, computer organisation basics.
- Control Systems: transfer functions, stability, frequency response, compensators, state-space.
- Communications: random processes, analog and digital modulation, information theory, error control.
- Electromagnetics: Maxwell's equations, wave propagation, transmission lines, waveguides, antennas.
How to prepare (free, in order)¶
- Networks and signals first: they feed control and communications.
- Solve the official papers of past years (the organising IIT's site publishes them with answer keys).
