Overview of GATE ECE Syllabus 2026

The GATE syllabus for ECE is designed to test conceptual clarity, analytical ability, and problem-solving skills across aptitude, mathematics, and electronics-related subjects. The exam balances theoretical understanding with numerical application, making it essential to prepare all areas systematically.

However, the overall structure of the gate syllabus for ECE helps candidates understand how marks are distributed across aptitude, mathematics, and core technical subjects. Knowing this structure early allows aspirants to allocate time proportionally and avoid over- or under-preparing any section.

The GATE ECE paper is a 100-mark computer-based test consisting of:

• General Aptitude – ~15 marks
• Engineering Mathematics – ~13 marks
• Core ECE Subjects – ~72 marks

The Gate ECE syllabus emphasizes conceptual understanding and numerical problem-solving, making clarity of fundamentals more important than rote learning.

GATE ECE Subject-Wise Weightage (Expected)

Understanding subject-wise weightage allows candidates to focus on topics that historically contribute more marks. The ECE topics of the GATE syllabus in 2026 include around 8 to 10 major technical subjects and an additional General Aptitude section. In the GATE EC examination, you will be asked three types of questions, including MCQs, MSQs, and NAT-based questions.
