GATE Electrical Engineering Syllabus: Subject-wise Explanation for Beginners
The complete official GATE EE syllabus (GATE 2027), explained in simple words: what each section covers, which topics beginners find hard, how subjects connect, and a checklist to track your preparation.
This post is part of our complete guide: How to Prepare for GATE Electrical Engineering from Scratch. Start there if you are new to GATE.
✅ The short answer
The GATE EE syllabus has three parts: General Aptitude (15 marks), Engineering Mathematics (13 marks) and nine Electrical Engineering subjects (72 marks): Electric Circuits, Electromagnetic Fields, Signals and Systems, Electrical Machines, Power Systems, Control Systems, Measurements, Analog and Digital Electronics, and Power Electronics.
⚡ In 30 seconds
- The official EE syllabus has 10 sections: Engineering Mathematics plus 9 EE subjects. General Aptitude is a separate syllabus common to all papers.
- Numerical Methods is not in the GATE EE mathematics syllabus.
- Electric Circuits and Mathematics are used inside almost every other subject.
- Tick a topic only when you can solve its PYQs, not when you finish its lecture.
GATE EE Exam Pattern in Brief
Before reading the syllabus, it helps to know how the marks are divided. GATE 2027 is organised by IIT Madras. The Electrical Engineering paper is a 3-hour computer-based test with 65 questions for 100 marks.
| Part | Marks | What it tests |
|---|---|---|
| General Aptitude | 15 | English, numerical, logical and spatial reasoning |
| Engineering Mathematics | 13 | Maths used in engineering |
| Electrical Engineering subjects | 72 | The nine core EE subjects |
Questions are MCQ, MSQ or NAT, worth 1 or 2 marks. Only wrong MCQ answers have negative marks. For the full pattern and how to plan your preparation, read our GATE EE preparation guide, and always confirm the latest details on the official GATE 2027 website.
General Aptitude Syllabus (15 Marks)
General Aptitude (GA) is the same for every GATE paper. It does not need engineering knowledge, only regular practice. Many students lose easy marks here because they leave it for the last month.
Verbal Aptitude
Basic English grammar: tenses, articles, adjectives, prepositions, conjunctions, verb-noun agreement and other parts of speech. Basic vocabulary: words, idioms and phrases in context. Reading and comprehension, narrative sequencing.
Quantitative Aptitude
Data interpretation: bar graphs, pie charts, 2D and 3D plots, maps and tables. Numerical computation and estimation: ratios, percentages, powers, exponents and logarithms, permutations and combinations, series. Mensuration and geometry. Elementary statistics and probability.
Analytical Aptitude
Logic: deduction and induction. Analogy. Numerical relations and reasoning.
Spatial Aptitude
Transformation of shapes: translation, rotation, scaling, mirroring, assembling and grouping. Paper folding, cutting, and patterns in 2 and 3 dimensions.
💡 Simple tip
Spend 30–45 minutes on GA once or twice a week from the start. Solve the GA questions from past GATE papers; they show the exact level asked.
Engineering Mathematics Syllabus (13 Marks)
Mathematics carries 13 marks directly, but it is also hidden inside many technical questions: eigenvalues in control systems, Laplace transforms in circuits, complex numbers in AC analysis.
| Topic | Official syllabus | Focus for beginners |
|---|---|---|
| Linear Algebra | Matrix algebra, systems of linear equations, eigenvalues, eigenvectors | Rank, solving equations, eigenvalue properties |
| Calculus | Mean value theorems, theorems of integral calculus, definite and improper integrals, partial derivatives, maxima and minima, multiple integrals, Fourier series, vector identities, directional derivatives, line, surface and volume integrals, Stokes’s, Gauss’s, divergence and Green’s theorems | Integration practice, Fourier series, vector calculus (needed for EM Fields) |
| Differential Equations | First-order equations (linear and nonlinear), higher-order linear equations with constant coefficients, variation of parameters, Cauchy’s and Euler’s equations, initial and boundary value problems, partial differential equations, separation of variables | Constant-coefficient equations (used in circuit transients) |
| Complex Variables | Analytic functions, Cauchy’s integral theorem and formula, Taylor and Laurent series, residue theorem, solution integrals | Residue theorem and contour integrals |
| Probability and Statistics | Sampling theorems, conditional probability, mean, median, mode, standard deviation, random variables, discrete and continuous distributions, Poisson, normal and binomial distributions, correlation and regression analysis | Conditional probability and standard distributions |
⚠️ Common confusion
Some websites list Numerical Methods for GATE EE. It is not in the official EE mathematics syllabus, so do not spend time on it for this paper.

| Differential equations | Mathematics | Circuit transients, Control Systems |
| Laplace transform | Signals and Systems | Circuit transients, Control Systems |
