Introduction About GATE ECE 2023
- Graduate Aptitude Test in Engineering (GATE) is a National-Level postgraduate engineering entrance exam for engineering graduate students. Usually, this is conducted by Indian Institute of Science, Bangalore and 7 other Indian Institute of Technology (IIT) located across India.
- It is conducted every year in the month of February and the next GATE entrance exam is expected to take place in the month of February 2023.
- This time it is IIT Kanpur that is going to conduct the GATE 2023. IIT Kanpur has released the syllabus for GATE Electronics and Communication Engineering 2023.
- Candidates who are appearing for GATE from Electronics and Communication Engineering discipline can refer the syllabus before they start their preparation.
