Which is better, electrical at BITS, Pilani, Goa or NIT, Calicut?

If you are financially stable, then you should prefer BTS Goa. NIT C has gotten worse in the following years. 

In NIT C, the students of some branches are getting back and the percentage of those back students are almost 50%. The environment of NIT C is hard to sustain and after being a Govt. Deemed University the faculty and students do whatever they feel like. Like one of the professors was given a warning after he was found guilty because of sexual harassment. 

NIT is known nationwide for the quality of students. It's not the Institute that makes a good student, it's rather the students that make an Institute good. The same is the case with NITs. If you want to join NIT, choose NIT Surathkal.

So, BITS is also a better option as compared to NIT Calicut which is as prestigious as IITs. One of the locations of BITS is Goa, which is indeed a dream destination for engineers. You will enjoy studying there. 

NIT Calicut has the cons mentioned above but not all the faculties are the same. Some of them are highly educated and decent.
