The Indian National Physics Olympiad (INPhO for short) is an Olympiad in Physics held in India. It is part of the selection process for the International Physics Olympiad.
The theory part of the INPhO examination is held in end-January/beginning February of every year. It is conducted by the Homi Bhabha Centre for Science Education. School students (usually of standards 11, 12) first need to qualify the National Standard Examination in Physics (NSEP) held in November of the preceding year. Among the 30,000+ students who sit for the NSEP, only the top 1% are selected for the INPhO.
