INO 2023 examinations are over.

Question papers and solutions are now available online on the HBCSE Olympiad website. Any comments regarding the same may be posted through the web interface only. Queries/comments in any other form (email/phone, etc.) will not be entertained.

Please note that while no individual response will be given, every comment/query will be considered by the Examination Board before finalizing the solutions. Any alternative method of solution to any question that is scientifically and mathematically correct, and leads to the same answer will be accepted with full credit. Partially correct answers will gain partial credit. For questions requiring reasoning or calculations, full credit will be given only if adequate justification and necessary steps of the calculations are written.

Please login here after February 17, 2023 to check your INO score. Performance cards will NOT be sent by post. Re-evaluation requests will only be accepted online (after logging in here) between February 17 and February 22, 2023.

Candidates who did not provide sufficient documentary proof of their identity or date of birth during INO examinations, and were instructed to send the same to HBCSE at ino@hbcse.tifr.res.in, please do so at the earliest (before February 7). Otherwise, your INO score will be invalidated.
