Are IIT Roorkee ECE course and IIT BHU Electronics similar in syllabus??
First of all as the name suggests IIT Roorke offers Electronics and Communications Engineering whereas IIT BHU offers Electronics Engineering so definately some of the courses on Communications systems would be replaced by more core Electronics subjects. Placements do not vary much if we consider both the instititutes.
You can see a detailed course plan of each of these programs which is available on the official website of the institutions.
