The Mathematics Olympiad is conducted under the aegis of the National Board of Higher Mathematics (NBHM).

From the Olympiad year beginning August 2008, a new integrated National Steering Committee for science and astronomy Olympiads has been overseeing the entire activity in these subjects. The subjects includes physics, chemistry, biology, astronomy, and junior science. The Olympiad programmes in physics, chemistry, biology, astronomy (junior and senior level) and junior science are a five stage process for each subject separately


Homi Bhabha Centre for Science Education is the nodal centre of the country for Olympiad programmes in mathematics and sciences including astronomy. The programmes aim at promoting excellence in science and mathematics among pre-university students.

The first stage for each subject is organized by the Indian Association of Physics Teachers (IAPT). All the remaining stages are organized by Homi Bhabha Centre for Science Education (HBCSE).

The programme is financially supported by Government of India, in particular, by Board of Nuclear Sciences (Department of Atomic Energy), Department of Science and Technology, Department of Space and Ministry of Human Resource Development.


Student studying in class 11th and 12th std are eligible.

Stage I: National Standard Examination in Physics (NSEP/NSEC/NSEB)


The physics/chemistry/biology Olympiad program follows the following 5 stages:

  • NSEP/NSEC/NSEB is the first stage of selection of students in the chemistry Olympiad Programme which is organised by the Indian Association of Physics Teachers (IAPT).
  • Every student aspiring to go through successive stages of the programme must enroll for NSEP/NSEC/NSEB.
  • NSEP/NSEC/NSEB is held at a large number of centres in the country.
  • The question paper will consist of 80 multiple choice questions, each with only one of the four options correct.
  • Language:English.
  • PHYSICS subject have subjective paper also.

Stage II: Indian National Physics/Chemistry/Biology Olympiad (INPhO/INChO/INBO)

Stage III: Orientation cum Selection Camp (OCSC) in physics,chemistry,biology

Stage IV: Pre-departure Training Camp (PDT) for IPhO/IChO/IBO

Stage V: Participation in International Physics/chemistry/biology Olympiad (IPhO/IChO/IBO).


Each item carries 3 marks. For each correct response the candidate will get 3 marks.

For each incorrect response one mark will be deducted from the total score.

No deduction from the total score will, however, be made if no response is indicated for an item in the answer sheet. The candidates are advised not to attempt such item in answer sheet, if they are not sure of the correct response.

More than one answer indicated a question will be deemed as incorrect response and will be negatively marked.


The syllabus for NSEP/NSEC/NSEB is broadly equivalent to the senior secondary level (Class XI and Class XII) of CBSE BOOKS for respective subjects. This is only a rough guideline and there is no detailed syllabus given.
