The result for the year 2021 was announced in March. The dates for the next year, 2022, have not yet been confirmed; they will be released soon and officially.

Frequently Asked Questions on InChO – Indian National Chemistry Olympiad


What is the InChO curriculum?

The InChO Syllabus for is divided into four sections. Here are some of them:
Organic Chemistry
Inorganic chemistry
Experimental Chemistry

What are the advantages of this exam for students?

Students who are interested in chemistry would profit much from this Olympiad. This Olympiad is a fantastic opportunity for students to share their thoughts and expertise in the subject of chemistry, and they may also demonstrate their understanding on this platform. Through this exam, rankers are rated and internationally recognised. By taking the InChO test, students build confidence in their ability to take the ICHO exam.

What should students do to get ready for InCho?

Students taking InCho must have a strong understanding of chemistry. They need to be adept in secondary chemistry, and should have a good understanding of the fundamentals. As a result, it is advised that students review the concepts covered in Chemistry in grades 7 through 10 before moving on to Chemistry in grades 11 and 12.

After passing InChO, what is the next step?

After passing InChO, a student moves on to the third level, OCSC, or Orientation and Selection Camp in Chemistry. The OCSC test is held every year between April and June, although it has been postponed this year.
