Keep the following ready:
Your registered email ID
Application detail
Personal identification document
Students should also cross-verify their name, exam centre, and reporting time on the admit card.
1. Strengthen Fundamental Chemistry Concepts
INChO questions rely heavily on theory, so clarity in Physical, Organic, and Inorganic Chemistry is essential.
2. Practice INChO Previous Years Papers
Working through past papers helps students understand the exam’s analytical style and difficulty level.
3. Build Speed with Accuracy
Since the paper includes multi-step solutions, time management is crucial.
4. Go Beyond the Textbook
Consult advanced reference books, Olympiad-level problem banks, and conceptual notes.
5. Revise Topics Covered in NSEC
Most INChO questions build upon concepts assessed at the NSEC stage.
