Each of us requires a different kind of study program based upon our style/preference of studying. Normally, all students take our study material and test series. Many also take video lectures as it helps them clear concepts. A lot depends upon time available to prepare, current stage of preparation, etc. If you are still unsure, please contact us.

Yes, there may be few scholarships available for students from top colleges, students with good grades, students from EWS and for students whose parents are from teaching or defence services. Pls contact us on 9930406349 via whatsapp with details of course you wish to join and scholarship category needed, along with relevant documents.

As a registered Career Avenues student, you can ask your doubts here and our faculty will get back to you.

Typically 5-6 months are required, but some students need a longer time frame based on other commitments. College students start preparation 12-18 months before GATE to have more time to practise questions as they may have semester exams as well.

We suggest about 800 to 1200 hours of preparation time overall. This can be divided into 3-4 months or 12-18 months, based on your schedule.

A Good Score For GATE Electronics (EC) is considered To Be: 55

**Steps And Strategy To Prepare For GATE Electronics (EC) Exam**

- Take a diagnostic test â€“ best diagnostic test is a GATE paper of any of the previous 3 years.
- Note down what you have scored and what was the actual GATE qualifying score cut-off. Note that qualification does not help you much. What you need is a good score. So note the good score mentioned above and measure the gap between your score and a good score.
- Note the GATE syllabus and mark your topics that you are good at. First try to master subjects that you are good at.
- However, some subjects like Networks, Signals and Systems, Analog Circuits, Electromagnetics, Control Systems and Communications have a high weightage. So you should definitely prepare these.
- General Aptitude does not require preparation. It requires practice. So just practice solving Aptitude questions every day for 30 minutes.
- Mathematics may have a very high weightage. But note that to get these 6-10 marks, what you have to study and practice is typically more than a core subject. So if you wish to eliminate some topics in Maths, it is fine. Master topics that you are good at.
- Take lots of section tests and Mocks. Career Avenues provides an excellent test series for GATE Electronics (EC).
- In case you require focused GATE study material and books, you should take Career Avenues GATE Electronics (EC) study material which has been made by IIT alumni and is focused towards GATE.Â

- Being a GATE aspirant, it is very important that you first know what is the syllabus for GATE Electronics (EC) Examination before you start preparation.
- Keep handy the updated copy of GATE Electronics (EC) Examination syllabus.
- Go through the complete and updated syllabus, highlight important subjects and topics based on Past GATE Electronics (EC) Papers and Weightage plus your understanding of particular subject or topic.
- Keep tracking and prioritising your preparation-to-do list and the syllabus for the GATE Electronics (EC) examination.
