I believe B.Sc in Environmental Science at Ramanujan College, Delhi University will be a bettet option than the latter. Ramanujan College counts among one of the better colleges of Delhi University with good infrastructure, faculty and other facilities. Environmental Science itself is a much interesting subject with a lot of career scope and prospects. Even if you want to prepare for Government Examinations like UPSC, JAM or GATE, you can as the curriculum is much relaxed and student friendly.
