Hi there, I am a HS passout in India and gave various engineering entrance examinations((IIT JEE, AIEEE, etc.)) this year. I want to know if it is possible to do MSc in Physics from IITs or some institute after doing B. Tech? I want to have a career in Astronomy and Astrophysics but there are no related courses available at undergrad level in India and I will have to get a BSc/MSc first. I also have the option of 5 year integrated MSc fron NIT Rourkela and 5 year integrated MSc from BIT Mesra((the latter has an exit option after three years where you passout with a BSc degree, if I have to take up this course I will take this option and then try to get in an IIT for MSc)) All advice will be appreciated. Thanks.
