This covers the pure sciences — physics, chemistry, the biological sciences, mathematics and statistics — and the research careers built on them. It runs from laboratory and field science to academia, and into the national research establishments that employ scientists directly.
How you get in. A three or four-year B.Sc after Class 12 with science, through CUET or a university entrance, or an integrated five-year M.Sc at an IISER, NISER or a central university. Research proper begins at master's level and is entered through CSIR-NET, GATE or an institutional entrance, with a PhD following. The Junior Research Fellowship attached to NET is what makes a research degree financially possible for most people.
Where the work is. University and college teaching, which requires NET or SET and increasingly a PhD; the national laboratories and research organisations — ISRO, DRDO, BARC, CSIR institutes, ICMR — recruited through their own examinations; industrial research and development in pharmaceuticals, chemicals, materials and energy; analytical and testing laboratories; scientific data and computational roles; and science writing, publishing and outreach.
The honest part. A research career is long and financially thin for years. A PhD takes four to six years on a fellowship stipend, postdoctoral positions are temporary, and a permanent research or faculty post typically arrives in your thirties if it arrives. The people who thrive are the ones who wanted the work itself, not the title. Everyone else should know that a B.Sc alone leads to a narrow set of options, and that the graduates who do best either continue to a master's and beyond, or pivot deliberately — into data and analytics, into industry quality and regulatory roles, into teaching, or into the many government examinations that any graduate can sit. Decide which of those you are doing by the second year of the degree rather than in the final semester.
