GATE 2026 Electronics and Communication Engineering Exam Preparation Tips
What should be my revision strategy for GATE ECE?
Revision plays an important role in preparation so you must start your revision after completing each topic. You can start your revision from chapters like Circuit Theory, Control Theory and Signal Processing as these chapters are related to other chapters. Starting with these chapters can build the knowledge which you can apply when you study other chapters. Start with these chapters and then move towards complex subjects like Power Systems, Measurements, Machines etc.
What can be the subject sequence for ECE?
Determining the subject sequence can ease exam preparation. It can help you to complete the syllabus on time along with the revisions. A sequence of readings is suggested below.
| Category 1 Subject | Category 2 Subject | Category 3 Subject | Category 4 Subject |
|---|---|---|---|
| Engineering Mathematics | Control System | Communication | General Aptitude |
| Network Theory | Digital Circuits | Electromagnetics | - |
| Signals and Systems | Analog Circuits | - | - |
| EDC | - | - | - |
Should I practice PYQs and take tests?
Solving PYQs and taking tests not only gives you an idea of exam patterns but also enhances your speed and accuracy. After completing all the chapters in each subject you must solve PYQs and take online or offline tests. After the final revision, you must solve the entire question paper within a time limit. You can solve one to two papers per day till the exam day.
