Syllabus of INPHO on Vedantu

Due to Covid 19 - The usual three-stage procedure for the selection of the teams to represent India at the International Olympiad that has been followed in prior years is now being shortened to a two-stage procedure as a one-time exception only for the academic year 2021 - 22. Read more about IOQ 2021-22.


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 2021 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 2021.


About InPhO

InPho or the Indian national physics olympiad is conducted by the Indian Association of physics teachers (IAPT), it was first conducted in 1987, the Indian national physics Olympiad has its own website where you can find the important latest information related to this Olympiad. The Indian national physics Olympiad is conducted every year on the last Sunday of January or the first Sunday of February, for the higher secondary level students. There are a total of five stages of the Olympiad programme for physics in India, Indian national physics olympiad or InPho is the second stage in the five-stage program. The five stages of the olympiad programme for physics in India are- National Standard examination in physics(NSEP), The Indian national physics Olympiad (InPho), The orientation cum selection camp (OCSC), the Asian Physics Olympiad (APho), The pre-departure training camp (PDC).


In order to be eligible to give the Indian national physics Olympiad students need to clear phase 1 of the olympiad plan laid out for physics.

10. How difficult is InPho?

InPho is a difficult exam. To do well, you need to have a strong foundation in Physics and Mathematics. Students should be well-versed in the curriculum of their degree, and it is beneficial if they have a strong foundation within natural sciences and mathematics. They should also read the information about the competency of each faculty member (e.g., in Physics, they need to know some basics like the kinetic theory of gases, electromagnetism and atomic physics). It is easier for them to do well if they have good knowledge of the syllabus.

11. What does InPho require?

The syllabus requires a strong foundation in Physics and Mathematics, good knowledge of the curriculum of the degree and an understanding of the layout of the question paper. Students should be familiar with how to solve the Physics and Mathematics questions. Vedantu provides a list of practice questions and a test series to help students practise for their InPho and help them understand the subject material. Students can also ask Vedantu for help with their InPho or they can sign up with Vedantu's InPho subject experts to clear their doubts.

12. Do we need to know everything in InPho?

No, students only need to focus on topics that are relevant to their study area as well as those which they need to know well for their examination. However, they should also try and read the whole syllabus as there might be questions that are not related to their study area and they will have to understand those topics to answer them. Vedantu provides practice questions, along with explanations and detailed notes to help students understand the topics better.

13. What is the best way to prepare for InPho?

Read a lot about Physics and do questions from previous years. This will give students an idea of what to expect. Students should also try and understand the syllabus well to fill in any gaps they might have. Finally, students must be calm on the day of the exam, so their positive attitude carries them through. Our team of InPho subject experts as well as our online test series can also help students prepare for their exams.

14. What is the best way for a student to monitor their progress?

You can have a study schedule and monitor your progress. It is also helpful if students ask themselves how much they know about the subject and try to fill in the gaps in their knowledge as well as doing questions from previous years. Students can also look at the syllabus and see if there are any topics that they would like to focus on. In addition, InPho Syllabus 2021 is available on Vedantu for students to download and refer to. Students can also ask their teachers questions based on InPho material or sign up with a tutor to go through Vedantu's InPho test series to understand their strengths and weaknesses.
