InPho Syllabus 2020

InPho 2020 Syllabus PDF

The INPhO exam is the second stage for the first five stages of the Olympiad Exam for Physics in India. It eventually leads to the selection of the International Physics Olympiad exam.

The INPhO exam organized by the Homi Bhabha Center For Science Education is usually conducted on the last Sunday of January or the first Sunday of February each year for the higher secondary level students. Students of class 11 and 12 need to first attempt the NSEP exam to be eligible for the INPhO exam. This exam serves as a means to select candidates for the Orientation- Cum-Selection -camp in Physics as well as to represent India for the International Physics Olympiad exam.

Similar to the NSEP exam, the Indian National Physics Olympiad Syllabus 2020 is also similar to the syllabus of class 11 and 12 (CBSE Board). The questions asked in the exam from the INPhO Olympiad Syllabus are subjective and are highly complex as similar to the questions asked in the International Physics Olympiad exams (IPHO). For this particular matter, the syllabus of IPHO should also be considered for the INPhO exam.


INPhO Syllabus 2020

The INPhO syllabus 2020 includes 7 subjective questions which should be solved in the duration of 3 hours. Earlier the INPhO syllabus was similar to the IPhO but now it is quite similar to the NSEC exam. The INPhO syllabus has been changed for the convenience of students preparing for the IITJEE and the Physics Olympiad at the same time.


Detailed INPhO Olympiad Syllabus  2020
