If NEET didn't get you a medical seat
A B.Sc through CUET (UG) is open with the same Class 12 subjects. Biology, Chemistry and Physics are all CUET domain tests.[3]

B.Sc (Bachelor of Science)
How long is a B.Sc in India, how do you get admission, and what comes after it?
B.Sc, the Bachelor of Science, is a 3-year degree after Class 12 in UGC's 2014 list of specified degrees. Under UGC's credit framework a fourth year gives an honours degree, and students with 75% over the first six semesters can do that year as honours with research. Central universities admit on CUET (UG) scores. After the degree, JAM is the entrance for M.Sc and related programmes at the IITs, and it is open to final-year students.

B.Sc stands for Bachelor of Science. UGC's 2014 gazette lists it, with B.Sc (Hons), under the sciences as a Bachelor's degree of at least three years after Class 12. You study one or two science subjects in depth, such as Physics, Chemistry, Mathematics, Botany, Zoology or Statistics. It is the entry point for an M.Sc and, after that, a Ph.D.[1]
It tends to suit you if
- You enjoy one science subject enough to study it for three or four years, not only to clear an entrance.
- You're thinking about research or an M.Sc. The fourth year with research and JAM both start from a B.Sc.
- You want a degree that keeps the graduate-level government exams open while you decide.
You may struggle if
- You expect a job title at the end of the degree itself. Most B.Sc routes lead into a Master's, a professional course or a recruitment exam.
- You dislike lab work and long problem sets. Science majors usually have both in every year.
This is a guide to the work the route asks of you, not a test of ability.[2]
- Class 12 with ScienceStage
UGC sets Class 12 as the entry level. The university sets subject and marks rules.
- CUET (UG) or the university's own admissionEntrance
Central universities use CUET (UG) scores. Pick the science tests the programme asks for.
- B.Sc: 3 years, or 4 with honoursCourse
120 credits for the degree, 160 for honours, under UGC's credit framework.
- JAM in the final yearEntrance
Final-year students can sit JAM for M.Sc and related programmes at the IITs.
- M.Sc, research, work or a government postWork
A 2-year M.Sc, an integrated Ph.D., a job, or the graduate-level government exams.
UGC's 2014 gazette lists B.Sc and B.Sc (Hons) as Bachelor's degrees with a minimum of three years and Class 12 as the entry level. The M.Sc that follows is a 2-year Master's.
Under UGC's Curriculum and Credit Framework, the 3-year degree needs 120 credits and the 4-year honours degree needs 160. If you have 75% or more across the first six semesters, you can spend the fourth year on a research project worth 12 credits and graduate with honours with research. The department needs at least two permanent faculty members recognised as Ph.D. supervisors to run that option, so not every college will offer it.[2]
UGC's framework names the degree after your major. For a single major you need at least half your credits from it: 60 of 120 for a 3-year B.Sc in Physics, 80 of 160 for the 4-year version. A second major needs at least 40%: 48 of 120 credits, or 64 of 160.
Some universities offer a multidisciplinary B.Sc instead, such as B.Sc in Life Sciences, with the core credits spread across Botany, Zoology and Human Biology. Your university's Board of Studies and Academic Council decide the course list.[2]
Central universities, and the state and other universities that take part, admit on CUET (UG) scores. You can take up to five tests, counting languages and the General Aptitude Test. Each domain test has 50 questions and runs 60 minutes.
Each university decides which CUET tests and Class 12 subjects its B.Sc needs, and the rule can differ between a B.Sc in Physics and a B.Sc in Life Sciences at the same university. Read the programme page before you pick your five tests.[3]

For a Master's at the IITs, the entrance is JAM. JAM 2027 has seven test papers (Biotechnology, Chemistry, Economics, Geology, Mathematics, Mathematical Statistics and Physics) and covers around 3,000 seats at 23 IITs for 2027-28, in M.Sc, joint M.Sc-Ph.D. and integrated Ph.D. programmes, among others. IIT Kharagpur runs it this year, and the exam is on 14 February 2027. Final-year students can sit it, and the IITs admit on JAM scores without a further test or interview.
JAM scores also count for over 2,000 postgraduate seats outside the IITs, at IISc, the NITs, IISER Pune, IISER Bhopal and other institutes, which admit through centralised counselling (CCMN) without a further test or interview. Each programme sets its own Minimum Educational Qualifications, so check that your B.Sc subjects match before you choose a test paper.[5]
The usual ladder is B.Sc, then a 2-year M.Sc, then either work or a Ph.D. JAM's joint M.Sc-Ph.D., dual-degree and integrated Ph.D. programmes join the Master's and the doctorate into one admission.
For government work, most graduate-level exams take a degree in any subject. Some posts ask for specific subjects in the degree; the recruitment notice for each exam lists them.[5]
If your JEE rank didn't reach the B.Tech branch you wanted
A B.Sc in Physics, Mathematics or Computer Science keeps you in the subject, and JAM opens M.Sc and integrated Ph.D. seats at the IITs after it.[5]
B.TechIf you have to stop after one or two years
Under UGC's framework, 40 credits plus a summer vocational course earn a UG certificate, and 80 credits plus one earn a UG diploma. You can come back within three years and finish within seven.[2]

Tips and tricks
- Choose your five CUET tests from the programme pages, not from habit. A B.Sc in Physics and a B.Sc in Life Sciences at the same university can ask for different tests.[3]
- If research interests you, track your marks from the first semester. The honours-with-research year needs 75% across the first six semesters, so a weak first year counts.[2]
- Ask before you join whether the department offers the honours-with-research year. UGC requires two permanent faculty members recognised as Ph.D. supervisors to run it.[2]
- Pick your JAM paper from the M.Sc you want, not from your favourite subject. Each IIT programme lists its own Minimum Educational Qualifications, and some need Mathematics in the degree for at least a semester or a year.[5]
- Keep every semester marksheet. JAM admissions ask for marksheets of all semesters, and final-year students must show the pass proof within the institute's deadline.[4]
Questions people ask
Is B.Sc a 3-year or 4-year course?
UGC lists it as at least 3 years after Class 12. Universities that follow UGC's credit framework add an optional fourth year for an honours degree with 160 credits.[2]
What is B.Sc Honours with Research?
It is the 4-year B.Sc where the fourth year includes a research project or dissertation worth 12 credits. UGC opens it to students with 75% marks or more in the first six semesters, at departments that have the faculty to supervise.[2]
Which CUET subjects should a B.Sc applicant take?
It depends on the university and the programme. The science domain tests are Physics (322), Chemistry (306), Mathematics/Applied Mathematics (319) and Biology/Biological Science/Biotechnology (304), and you can take up to five tests in all.[3]
Can I do an M.Sc at an IIT after a B.Sc?
Yes, through JAM. JAM 2027 covers around 3,000 seats at 23 IITs for 2027-28. You need to clear the cut-off in a test paper and meet the programme's own subject rules.[5]
Can I sit JAM in the final year of my B.Sc?
Yes. The JAM 2027 brochure accepts candidates in the final year of their undergraduate degree, as long as they submit proof of passing within the admitting institute's deadline.[5]
Is a B.Sc a good Plan B after NEET?
It keeps you in science with the same Class 12 subjects, and CUET (UG) has Biology, Chemistry and Physics tests. Whether it suits you depends on whether you would still enjoy the subject without the medical goal.[3]
