Olympiads Physics

Physics

The International Physics Olympiad (IPhO) is an annual event, which is held in the month of June - July every year.  The country of the venue of IPhO varies from year to year. This activity has been conducted regularly for the past 37 years.  However, India began to participate in the IPhO only in 1998.
The IPhO is a keenly contested examination in physics open to pre-university students of all countries in the world. It serves as a bench-mark for study of physics at pre-university level. It also fosters friendly relations amongst students of different countries. 
It is believed  that India's participation in the IPhO  boosts the level of science education in the country.The physics olympiad programme in India aim to promote excellence in physics at the pre-university stage and to select and train participants for the IPhO.
To know the five stage process of this program

Stages


The physics Olympiad program follows the following 5 stages:
  •  Stage I: National Standard Examination in Physics (NSEP),
  •  Stage II: Indian National Physics Olympiad (INPhO),
  •  Stage III: Orientation cum Selection Camp (OCSC) in physics,
  •  Stage IV: Pre-departure Training Camp (PDT) for IPhO,
  •  Stage V: Participation in International Physics Olympiad (IPhO).


Stage I is entirely the responsibility of IAPT. All the remaining stages are organized by HBCSE.
The detailed information about eligibility and structure of the stages is given below:
  

Stage I: National Standard Examination in Physics (NSEP)


NSEP is the first stage of selection of students in the physics 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.  NSEP is held at a large number of centres in the country.

Date of NSEP 2010:             28 November 2010 (Sunday) 
Time of NSEP 2010:            09:30 am to 11:30 am
Last Date for Enrollment for NSEP:    15th September 2010

Eligibility:
All Indian students who are born on or after July 1, 1991 and, in addition, are in Class XII or lower as of November 30, 2010, are eligible to appear for NSEP 2010 -- 2011. A student may appear for more than one subject provided the examination schedule allows it. See information about the examination schedule under various subjects. Students who have passed Class XII are not eligible to enroll for NSEP.
It is the student's responsibility to ensure that the eligibility criteria are satisfied. In case at any stage of the programme it is found that the student does not satisfy the eligibility criteria, he/she may be disqualified from the programme.

Syllabus:
The syllabus for NSEP is broadly  equivalent to the senior secondary level (Class XI and Class XII) of CBSE Physics. This is only a rough guideline, and there is no detailed syllabus given for NSEP.

Question Paper:
NSEP emphasizes comprehension of the subject, not rote memory.  Its format is as follows:




Part A (180 marks): 50 multiple choice questions consisting of:
 (A1) 40  questions, each with only one of the four options correct
 (A2)
10 questions, each with one or more than one options correct. To get credit, all correct option(s) and no incorrect option(s) should be marked.
Part B (60 marks):  5 (or 6) questions which are problems or short-answer type. All questions carry equal marks.
Language: English. (However,  NSEP question papers may be available in  Hindi, and some other regional languages provided there are more than 300 students for that language. Please check with IAPT.)

     
Qualifying for the Second Stage:
Based on performance in NSEP, the top 300 students in order of merit qualify to appear for the Second Stage of the Olympiad programme (INPhO). In case there is a tie at the last position, all students with the same marks qualify for the INPhO.
All students who qualify to appear for the INPhO get a certificate of merit from IAPT.

Stage II: Indian National Physics Olympiad (INPhO)


INPhO is organized by HBCSE at about 15 centres in the country.

Eligibility: Students selected from Stage I examination (NSEP) are eligible to appear for INPhO. In addition, those students, who have been exempted from NSEP as described in the Enrollment page, are also eligible to appear for INPhO. Besides these two, there is no other way by which a student becomes eligible to appear for INPhO.

The tentative date and time of INPhO 2011 examination are as follows:

January 30, 2011 (Sunday) :          09:00 am --- 12:00 noon (3 hours)

The confirmed date and schedule will be announced in the first week of January 2011 on this website and communicated by post to the eligible students.  Students appearing for INPhO are eligible for TA/DA as per norms of the programme.

Syllabus : The syllabus for INPhO is broadly similar to NSEP.
The syllabus, however, is only a broad guideline. Questions and problems in National Olympiads are usually non-conventional and of high difficulty level, comparable to International Olympiads.

On the basis of performance in INPhO, the top 35 students in the merit list will be selected for Stage III: Orientation Cum Selection Camp (OCSC) in physics.
In the event, there is a tie at the last position, all students with the same marks at this last position will qualify for OCSC.
There will be no other criterion or provision for selection to OCSC.


Stage III: Orientation  Cum Selection Camp (OCSC) in Physics


OCSC in physics will be organized by HBCSE sometime in April to June 2011 for 2-3 weeks. The precise dates will be announced prior to or along with the announcement of the selection list for the OCSC.

Eligibility for OCSC : Only the students selected from the merit list of Stage II (INPhO) are eligible. There will be no other criterion or provision.

The camps include several theoretical and experimental tests.  Orientation is provided to students especially in experiments. The camps conclude with a valedictory function  where distinguished scientists are invited to speak to the students.

The merit list of OCSC is prepared on the basis of the combined theoretical and experimental score aggregated over all the tests in the camp, with 60% weightage for theory and 40% weightage for experiment. Performance in previous stages (NSEP and INPhO) will not be a consideration for the merit list and awards of the OCSC.

The top 5 students in the OCSC physics merit list are declared to be special merit awardees. These special merit awardees are given Rs. 5,000/- each in the form of books and cash. In addition there are special prizes to recognize meritorious performance in theory and experiments.

The 5 special merit awardees in physics selected at the end of the OCSC constitute the 5 member student team for the International Physics Olympiad (IPhO), provided they satisfy required criteria such as age limit, holding valid Indian passport, medical fitness, parental consent, etc.

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

The selected 5 member  Indian team undergoes a rigorous training programme at HBCSE in theory and experiments. Special laboratories have been developed at HBCSE for the purpose of experimental training. Resource persons from HBCSE and different institutions across the country train the students.


Stage V: Participation in International Physics Olympiad (IPhO)

The 5 member student team, 2 teacher leaders and 1 scientific observer constitute the delegation to represent India at the International Physics Olympiad (IPhO).
The 42nd  IPhO will be held in Bangkok, Thailand tentatively in July 2011.
