The Graduate Aptitude Test of Engineering (GATE) is a highly competitive exam conducted by 7 IITs and IISc to evaluate the technical reasoning of engineering graduates. So, if an engineering graduate is willing to appear in GATE for Electronics and Communication, they should first analyse the entire GATE 2024 syllabus for Electronics and Communication. Based on the frequency of questions asked, they should also clearly list out the marks and weightage of all the subjects. A list of all the subjects for electronics and communication along with their marks weightage as per the latest trend in GATE are mentioned below:

How to approach the GATE 2024 syllabus for Electronics and Communication?

After critically analysing the syllabus, the next step is to decide the sequence of reading the subjects.  All the technical subjects for Electronics and Communication can be classified into three groups – namely Group-1 (Mandatory), Group-2 and Group-3.

Group 1 subjects are the primary subjects which build the foundation for subjects in Group 2 and Group 3. Hence, starting with these subjects is key to gaining a deeper understanding of all the concepts. 

For example, the basics of Network Theory and Electronic Device Circuits are prerequisites to read Analog electronics efficiently. Likewise, the basics of signals and systems are necessary for reading Control Systems and Communication.

For General Aptitude, you can take any of the two methods: either study it along with Group 1 subject or keep five days reserved every month for finishing some chapters. 

After finalising the sequence, an aspirant should have adequate and precise study material containing a detailed explanation of the concepts and practice questions. IMS GATE Academy has one of the best study materials containing proper explanations of concepts and relevant theories concerning the GATE. We provide theory books and exercise books for all the subjects. In our exercise books for every subject, questions are well-placed in different chapters. Questions for every chapter are categorised as Levels 1, 2, and 3 based on the difficulty level. You can fill out the form here to learn more about the program.
