InPhO Syllabus

The second level of India’s five-stage physics Olympiad program is called the Indian National Physics Olympiad (INPhO). Selection for the International Physics Olympiad is the result of it. For secondary school pupils who want to increase the breadth of their physics knowledge, they must take the exam. The IPhO is an international competitive exam that fosters global participation and acts as a benchmark for pre-university physics students. The main objective of the INPhO test is to raise student performance on the physics curriculum.INPhO Syllabus for Classes 11 and 12

Highlights of the Exam

The Homi Bhabha Centre for Science Education administers the INPhO exam, which is often given to upper secondary pupils on the final Sunday of January or the first Sunday of February each year. Students in grades 11 and 12 must first complete the National Standard Examination in Physics exam in order to be eligible for the INPhO exam. This test is used to choose candidates for the Physics Orientation, Curriculum, Selection, and Camp. It also serves as India’s representative in the International Physics Olympiad. The syllabus for InPhO is comparable to that of CBSE Board Classes 11 and 12.INPhO Syllabus for Classes 11 and 12

InPhO Syllabus

The INPhO syllabus and the NSEP syllabus are extremely similar. However, the syllabus is merely a general outline. Like International Olympiads, National Olympiad topics and problems are usually highly challenging and unconventional. Below is a discussion of each section’s INPhO Olympiad syllabus. To be ready for the INPhO test, students can utilize the INPhO Olympiad syllabus that is provided below. It is comparable to senior secondary education, which includes classes XI and XII.INPhO Syllabus for Classes 11 and 12
