igot 1238 rank iniit jee2012.i am not able to decide whether to take mech mtech dual in iitm or btech ee or ece in iitroorkee.please suggst me

If you have no interests or dislikes, always prefer the college with the stronger brand name. However, if youre interested in ECE or EE, instead of Roorkee, go for IIT BHU. With the IIT tag, with time (by the time you pass out), BHU will be ranked higher than Roorkee or Guwahati. Also, if youre placement-oriented, go for CSE @ BHU, it has placements as good as Bombay. Best of luck!
