Electronics at Private College vs. BSC Physics at Calcutta University for Astrophysics/Cosmology?

Ans: I would address your question in 3 parts. 1. Please pick a course for a career out of astrophysics and cosmology. 2. Run a rigourous test in terms of what it takes to puruse that career, check if you are fascinated by the nomenclature, do you have the aptitude and are willing to put in the rigour and determination to slog it and not turn back midway. 3. Having done that look for the best courses BSc or BTech and institutions offering programs at the level you pick (BSc or BTech), and order them in your personal preference of location, government, non government. And then make your choice. For genral guidance on whihc course and insitution to pick do run an eye an article I wrote on Rediff.com at https://bit.ly/4cZ1pA7
