NIT Durgapur will be better for an M.Sc Physics. The quality of academics and exposure offered is better than any of the non-tech institutes in the region. Most students prepare for competitive examinations like NET, GATE, JEST, BARC, ISRO, etc. NITD also has collaborations with many national institutes and research labs.
Yes, IIEST offers placements to MSc students. But the salary packages offered aren’t very high.
I know a little bit about NIT Durgapur, as my brother is a student there. Let’s talk about the prospect and opportunities for MSc at NIT Durgapur.
Like any other NIT, NIT Durgapur is a technical institute. It excels in the technical domain. You can definitely consider NIT Durgapur for your MSc in Physics. Be assured that you will get better academic results at the institute as compared to any non-technical institute. Being said that I think it will be even better if you start preparing for IIT JAM, that way you can take admission in leading IITs.
As for placement, there are hardly any placement opportunities available for MSc students.
