If you have taken admission you don't have to worry about that just give your best.

Good Luck!!

Both the specializations provide good opportunities in the market. How ever, manufacturing takes an edge over the latter because of its work environment. Even if you observe the cutoffs in IIT s and NITs, manufacturing is observed to have higher cutoffs compared to thermal.

But lastly, I would suggest you
