Dear Ankit ,

As your queastion clearly indicates that you are bit confused , so let me clearify you .

As you said that you would be scoring 185 in IIT JEE so with these marks you would  not be able to attain very good rank, as a result to get electrical or mechanical in IIT's would be really tuff for you.

Now if we talk about the comparison then definately ISM  is best for METALLURGY, IT bhu  would be the best option for electrical,

and definately if you made through NIT's then that would be also the best option for all the three branches.
