Dear candidate out of two options which makes it tuff for you to decide, NIT Surat is a very good college and M.Sc Physics curriculum is also nicely taught, but considering the future prospects I would suggest you to choose Metallurgy and Materials Science over this as the placement trends in College of Engineering,Pune is much better. The infrastructure is well established, labs are well equipped, Faculties of Metallurgy branch are extremely qualified. So overall your experience would be great, as a starting package the companies would offer you 6-8 LPA.
