Avoid going for Dual Degree Courses, unless youre generally interested in the Respective Subject. ECE at NIT Durgapur seems a good choice to me, or maybe BTech Mechanical or Electrical if you get at some of the Other Good NITs. NIT Durgapur has strong faculty, infrastructure, research facilities and placements as well as excellent study groups for Preparation for GATE, Etc.
