Tips to Study for the GATE ECE Syllabus

# Make a study plan. If you have already done network theory analysis and synthesis during your graduation, start off with the most important topics. If doing them for the first time, go in sequence.

# At the end of every topic, practice problems on that topic. Analyse your result.

# Check the concepts that you are weak in. If these topics are in the important topics or concepts list then go back and clear them up, if not, mark these topics, come back to them later after you are done with all the subjects.

# After you have finished the entire subject and have done so for others, solve full portion practice tests. Analyse your test scores in a similar manner as done for subject wise tests.

# After every test, analyse your result and work on the weak topics that hold the maximum weightage. This way you can finish all the subjects and topics inclusive if you have time, else at least you would have covered the important topics.

Guidance for Network Theory in GATE ECE Syllabus

If you have less time or if you are into a full-time profession, then doing all of this may be a time-consuming process. In that case, you can consider joining an online coaching class for your GATE preparations which will help you cover your GATE ECE syllabus in a shorter interval of time.

So, the main advantage of joining online coaching is that it can save a student a lot of time. Also, When one goes for a coaching class, they may not realize but a lot of time gets consumed in petty things like – waiting for a professor to come, sitting in a class and waiting for everyone to finish solving a problem, settling down of a noisy class, it becomes difficult to cope up in case a lecture is missed.

So, All these amounts to a significant time in a student’s preparation time and especially when a student has less time for preparation, these factors add as a hindrance.

Other Tips

GATE is considered to be one of the toughest exams. It is the doorway to pursue your higher studies in engineering from top universities. Many people even get hired depending on their GATE score. So there is no point of neglecting the preparations.

One of the important things that an aspirant should always keep in mind is that the GATE ECE syllabus is huge and one has to have a very realistic yet challenging study plan to cover the entire syllabus. Time management plays a vital role in achieving success in exams like this.

Make a proper study plan, keep the focus on your weak and strong points, look through previous year papers, and sit on as many mock tests as possible.


Hopefully, all your queries regarding the network theory study plan, GATE ECE syllabus covering tips, reference network theory books have been met in this article.
