The full form of INPhO is Indian National Physics Olympiad is the second stage of the five-stage Olympiad program for Physics in India. It ultimately leads to the selection of the International Physics Olympiad. The INPhO Exam is conducted on the last Sunday of January (or on the first Sunday of February), every year, by the Homi Bhabha Centre for Science Education. Students in school(usually the students of standards 11 and 12l) first need to qualify the National Standard Examination in Physics (NSEP) held on the last (or second last) Sunday of November of the preceding year. Among over 40,000 students that appear for the INPhO examination at almost 1400 centres all across India, around 300 to 400 students are selected for INPhO based on their scores and also based on regional quotas for the states from which the students appear. Different state-wise cut-offs exist for selection to INPhO. INPhO Exam serves as a means to select the students for OCSC (Orientation Cum Selection Camp) in the subject Physics, as well as to represent India in the Asian Physics Olympiad (APhO).
Most of the students qualifying the INPhO are those that are completing their twelfth standard. However, there have been some instances of students who have qualified INPhO at the end of the eleventh and very rarely, in the tenth standard itself.
The Physics Olympiad program has the following fives stages-
(Image to be added soon)
Stage I: NSEP- The full form of NSEP is National Standard Examination in Physics
Stage II: INPhO- The full form of INPhO is Indian National Physics Olympiad
Stage III: OCSC- The full form of OCSC is Orientation cum Selection Camp in physics
Stage IV: PDT- The full form of PDT is Pre-departure Training Camp for IPhO
Stage V: IPhO- The full form of IPhO is - Participation in International Physics Olympiad
Stage I, which is the National Standard Examination is entirely the responsibility of the Indian Association of Physics Teachers. All the remaining stages are organized by HBCSE. It is essential to qualify the NSEP Exam so as to participate in the INPhO.
The medium of the INPhO exam is bilingual that is the student can opt any of the languages which they want i.e. English or Hindi. As per the previous record, the exam of INPhO 2020 is conducted in the midweek of Feb or March. We will provide you the date of INPhO after it will release officially on the official site.
The procedure for the selection of students in Physics Stage II i.e., INPhO 2020 are:
The students are divided into two groups i.e. Group- A and Group- B. the students in Group A must be in class XII while the students in Group B must be in class XI or lower.
A separate Merit Index (MI) and Minimum Admissible Score (MAS) will be calculated for the two groups.
The question paper of NSEP 2019 and INPhO 2020 will remain the same for two groups.
A total number of 250 students from each group will be shortlisted for stage II of INPhO and therefore a total of 500 students will be selected.
The result of the INPHO will be available online on the official website of HBCSE. All the candidates are able to download their results by filling the details like NSE Roll Number, DOB, and the verification code.
The following details can be checked from the result.
Candidate’s Roll Number
Details of MAS and MI
Those candidates who will apply for the exam must need to pay the fees for the amount of Rs. 150/-. The fee is charged per student with the per subject. The fee will be paid at the NSE registration center.
The admit card of the physics exam of INPhO will be available and can be checked through the online mode. All the eligible candidates are able to download the admit card of INPhO from the official site before a few dates of the exam.

2. What is the Exam Pattern and Syllabus of the INPhO Exam?
Syllabus: As like NSEP, the syllabus for INPhO Exam is also based roughly on the school syllabus of class 9th and 10th (CBSE board).
NSEP exam does not emphasize rote memory, but the comprehension of the structure.
The format is as follows
Exam Pattern and Structure
Part A (180 marks)
50 Multiple Questions Consisting of
Each question consists of only four options where only one is correct.
Each question with one or more than one option can be right. To get credit, no incorrect option or options should be marked and all correct options or options must be marked.
Part B (60 Marks)
There are 5 or 6 questions are problems or short-answer type questions. All the questions carry equal marks.
However, the NSEP Exam question papers may be available in Hindi, and other regional languages provided that there are more than 300 students for that language. However, this has to be checked with IAPT.
3. What is INPhO?
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 the IPhO Exam varies from year to year. This activity has been conducted regularly for the past thirty-seven years. However, our country India began to participate in the IPhO Exam only in 1998.
The IPhO Exam is a keenly contested examination in physics open to pre-university students of all countries in the world. It serves as a benchmark for the study of physics at the pre-university level. It also fosters friendly relations among students from different countries.
It is believed that India’s participation in the IPhO Exam helps to boost the level of science education in the country. The physics olympiad programme in India, it aims to promote excellence in the subject physics at the pre-university stage and to select and train participants for the IPhO.
4. What is the Last Stage of the INPhO Exam?
Typically, the marks of several students are calculated by adding 40% of the marks scored in the NSEP Exam, as a percentage of the maximal marks attainable in the examination (generally 240) to 60% of the score in the INPhO Exam, as a percentage of the maximal marks attainable (varies from year to year). A list of the top 50 students is prepared, and the top 8, who are willing to appear for APhO, are selected.
