Well .. I had a similar kind of confusion last year.The thing is that some courses at some institutes are not good and some courses considered poor and quite good in them.There's no such thing as bad course as such.It is all based on the college.For eg. in NIT Bhopal, Civil,Electrical and Mech are the best courses. But in a few places, Civil is considered to be a bad course and IT is considered better than it. So ask a few friends in NITs about how the courses are and then choose them.

Well if u dint get me .. In short .. Its not always that ECE=CSE > MECH > ELEC > ... > Chemical > Civil > Metallurgy .. It depends on how good the course is in that particular college as well ! ..
Hope you got my point ..
