Science after Class 10
I want to take Science in Class 11. Which subjects should I pick so the entrance exams I might want later stay open?
Quick answer
Science in Class 11 is a set of subjects you choose. Under CBSE's scheme you take at least five subjects, with Hindi or English as one of your languages, and you carry the same subjects into Class 12. Which ones you pick decides which entrance exams you can sit two years later. Physics, Chemistry and Maths keep JEE Main open for engineering, architecture and planning. NEET (UG), the medical entrance, asks for Physics, Chemistry, Biology or Biotechnology, and English. If you take both Maths and Biology, both stay open. The rules below come from the official bulletins, so you can pick your Class 11 subjects knowing where they lead.

This page may be out of date. It was due for a re-check on 31 December 2026. Confirm every rule with the official source before acting on it.
The CBSE rules are for the 2026-27 session. The JEE Main and NEET (UG) rules are from the 2026 bulletins; the 2027 bulletins were not out when we checked on 1 October 2026.
Science after Class 10 means a group of electives you take for two years: Physics, Chemistry, Mathematics, Biology, Biotechnology, and computing subjects such as Computer Science. CBSE treats Class 11 and Class 12 as a single two-year course, so the subjects you start with are the ones you finish with.
Most students take Physics and Chemistry, then add Maths, Biology or both. That third subject decides which entrance exams you can sit at 17.[1]
Who it suits, and who struggles
It tends to suit you if
You like working a problem through on paper until it comes out right.
You don't mind lab work. In CBSE's scheme, Physics, Chemistry and Biology each give 30 of their 100 marks to practicals.
You want engineering or medicine to stay possible for two more years.
You may struggle if
You'd be taking Maths only to keep options open, and it was already a daily fight in Class 10.
You want to start earning or learning a trade soon. A diploma or an ITI gets you there faster.
Your real interest is history, business or art, and Science is the safe-looking choice.
This is a guide to the work the route asks of you, not a test of ability.[4]
The road
1
Pass Class 10Stage
Any board recognised in India.
2
Choose your Class 11 subjectsYour choice
At least five under CBSE's scheme, kept the same in Class 12. This is the choice that matters.
3
Class 12 with Science subjectsStage
Maths keeps engineering open. Biology keeps medicine open. Both keep both.
This is the combination that keeps every JEE Main paper open: Paper 1 for B.E./B.Tech, Paper 2A for B.Arch and Paper 2B for B.Planning.
What it requires: For NIT, IIIT and CFTI B.Tech seats, Class 12 needs Physics and Maths, one of Chemistry, Biology, Biotechnology or a technical vocational subject, a language and one more subject.
NEET (UG) is the entrance for MBBS and BDS, and NTA's bulletin also uses it for BAMS, BSMS, BUMS, BHMS and B.Sc. Nursing counselling. It asks for Physics, Chemistry, Biology or Biotechnology, and English.
What it requires: Physics, Chemistry, Biology or Biotechnology, and English in Class 12. You must turn 17 on or before 31 December of the exam year. There is no upper age limit.
Taking Maths and Biology together means you don't have to choose between JEE Main and NEET (UG) at 15. The cost is a heavier timetable. CBSE lists Mathematics and Biology as separate electives, so check that your school runs them in the same year.
What it requires: A school that offers Maths and Biology together in Class 11.
Science with Computer Science or Informatics Practices
CBSE offers three computing subjects: Computer Science, Informatics Practices and Information Technology. You can take only one. Any of them can sit alongside PCM or PCB as an extra subject.

Marks rule
Paper 1: B.E./B.Tech at NITs, IIITs, CFTIs
Physics, Maths, one of Chemistry/Biology/Biotechnology/technical vocational, a language, one more subject
75% aggregate (65% SC/ST/PwD) or top 20 percentile of your board
Paper 2A: B.Arch
Physics and Maths compulsory, plus one of Chemistry, Biology, a technical vocational subject, Computer Science, IT, Informatics Practices, Engineering Graphics or Business Studies
At least 45% aggregate (Council of Architecture rule)
Paper 2B: B.Planning
Maths and four other subjects (for NIT+ seats)
At least 50% in Maths and 50% aggregate

Class 12 marks each JEE Main paper asks for
Paper 1 also accepts the top 20 percentile of your board, or 65% for SC/ST/PwD. Paper 2B also needs 50% in Maths. Source[2]
17 by 31 December of the exam year; no upper limit[3]
Fees: Fees vary from one institution to the next. Check the institution's official fee notice before you apply.
A day in the work
For the next two years your work is study, and CBSE's marks scheme shows how it splits. Physics, Chemistry and Biology are 70 marks of theory and 30 of practical work, so a real part of your week goes to experiments and your practical record. Mathematics is 80 marks of theory and 20 of internal assessment, with no lab. Computer Science and Informatics Practices are 70 theory and 30 practical.
On top of the board exams, most students preparing for JEE Main or NEET (UG) study for the entrance separately. Plan the two years with both in mind.[4]
Growth
The ladder runs Class 12, then an entrance exam, then a degree. JEE Main Paper 1 leads to B.E./B.Tech, Paper 2A to B.Arch and Paper 2B to B.Planning. The medical side runs through NEET (UG), which the Class 12 PCB pathway covers.
From the degree you go to work or to a master's. Each degree page on this site covers its own next steps.[2]
If this door closes: Plan B
If Maths stops working for you in Class 11
NEET (UG) does not ask for Maths. Physics, Chemistry, Biology or Biotechnology, and English keep the medical route open.[3]
Dropping Maths at 15 means JEE Main is off the table at 17. Dropping Biology rules out NEET (UG). CBSE's scheme keeps the Class 11 subjects going into Class 12, so treat this as a two-year decision.
If your child is in a state board school, the subject rules come from that board, not CBSE. The entrance exam rules in the table above are the same whichever board your child sits.

Treat the Class 11 subject list as a two-year choice. Under CBSE's scheme the same subjects carry into Class 12.[1]
Keep Maths if engineering is even a maybe. NEET (UG) doesn't list it, but JEE Main B.Tech does.[2]
You can't take Mathematics (041) and Applied Mathematics (241) together.[1]
Hindi or English has to be one of your languages.[1]
Taking Maths and Biology together keeps both engineering and medicine open. Ask whether the school offers that combination before you take admission.[1]
On a state board, the subject rules come from that board, but the JEE and NEET entrance rules stay the same.
Questions people ask
Do I need Maths for NEET (UG)?
No. The NEET (UG) 2026 bulletin lists Physics, Chemistry, Biology or Biotechnology, and English. Maths isn't on that list.[3]
Can I do B.Tech with PCB?
Not through JEE Main for NIT, IIIT and CFTI seats. Paper 1 asks for Physics and Maths in Class 12. Biology can stand in for Chemistry, but nothing stands in for Maths.[2]
Is Applied Mathematics the same as Mathematics?
CBSE treats them as two separate subjects (codes 041 and 241), and you can take only one. If an entrance exam you might sit names Mathematics as a required subject, read that exam's bulletin before you choose Applied Mathematics.[1]
Can I take both Maths and Biology in Class 11?
Yes, if your school offers the combination. CBSE's scheme asks for at least five subjects, so Physics, Chemistry, Maths and Biology with English fits. Taking both keeps JEE Main and NEET (UG) open.[1]
