Dear aspirant,

If you would like to take my opinion I would recommend you to choose jadavpur for metallurgy but note this if you don't have a liking for coding only then go for this option.

If you want to go for the non core field I will suggest you to go for cse branch in nerist. Lastly for iiest shibpur , mining was considered to be the one of the best of iiest but the placements from the current few years is not good so I would ask you to go with cse or metallurgy.
