INChO Syllabus

Every year, the Indian Association of Chemistry Teachers hosts the Indian National Chemistry Olympiad (INChO). This is a competitive test in which people from all around the country compete to display their chemistry expertise. The test is held every year in the months of January and February.

It is critical to understand the curriculum before beginning your preparation. Once students know the curriculum, they may devote their whole attention to the preparation. The syllabus aids in the comprehension of the topics that must be addressed. As a result, students prepare according to the syllabus, and in this article, we will discuss the INChO Syllabus in detail.

Exam Pattern for the INChO Olympiad

The following is the exam pattern used by the INChO:

  • The question type comprises detailed queries that demand a descriptive answer.
  • The paper is written in both English and Hindi. At the time of registration, students can select their preferred medium.
  • The syllabus is identical to that of the higher secondary school curriculum, including the CBSE Class XII syllabus. INChO also follows the NSEC (National Standard Examination in Chemistry) syllabus.
  • The time limit for completing the paper is two hours.

Syllabus for INChO

The syllabus for INChO in 2022 is the same as last year. Students can use this as a starting point for their test preparation.

Students must be experts in the discipline of chemistry to participate in INChO. They must begin with the fundamentals of Class 7 to Class 10 to obtain experience and in-depth understanding. INChO’s curriculum is aligned with the most recent CBSE curriculum. To reinforce the fundamentals, one must have a firm grip on their school study materials from grades 11 and 12, including the NCERT.

Frequently Asked Questions on INChO Exam Syllabus

Is INChO solely dedicated to the study of chemistry?

Yes, INChO is solely dedicated to the area of chemistry. There are several other Olympiads for various topics, but INChO is the only one dedicated to Chemistry. Students worldwide take part in this competitive test to demonstrate their expertise in this discipline. Students take this test in order to acquire an international reputation in Chemistry.

What does IACT stand for?

The Association of Chemistry Teachers, abbreviated as IACT, is the successor of the Indian Association of Chemistry Teachers. Along with HBCSE, this organisation manages and conducts the Chemistry Olympiad for India. The Homi Bhabha Centre for Science Education, based in Mumbai, was the driving force behind the formation of this organisation.

What should students do to get ready for INChO?

Students taking INChO must have a strong understanding of chemistry. They need to be proficient in secondary chemistry, but they should also understand the fundamentals. As a result, students should review Class 7 to Class 10 Chemistry concepts before moving on to Class 11 and Class 12. Students can then practise using question papers from past years, sample papers, and relevant questions. By following these suggestions, students can score good marks in the examination

How challenging is INChO?

INChO is a one-of-a-kind Chemistry Olympiad that allows students to demonstrate their Chemistry knowledge and abilities on a global scale. Furthermore, since the test is designed for students in Classes 11 and 12, the difficulty level is moderate. This is acceptable because the Olympiad would represent our country’s kids on a global scale.
