Olympiads · exam hub
Olympiad preparation in India follows fixed stages: the science route starts with the National Standard Examinations (NSEP, NSEC, NSEB, NSEA, NSEJS), usually in late November, and the maths route starts with IOQM, usually in September, then RMO and INMO. BrainStride is an AI tutor for JEE, NEET and Olympiad preparation that runs a diagnostic, maps your weak chapters and writes a daily plan, with every solution checked by teachers.

The method
Olympiad problems punish shaky Class 11 basics. The diagnostic finds the chapters where your reasoning breaks before you spend weeks on hard sets.
NSEP, NSEC and IOQM-style problems chosen for the idea they test. Each wrong attempt is tagged — concept gap, wrong model, or arithmetic slip.
Every solution is audited by teachers before release. On RankLab, faculty-written problem sets and Sunday doubt clinics cover the harder road.

The first stage of the science Olympiads in India is the National Standard Examination: NSEP for physics, NSEC for chemistry, NSEB for biology, NSEA for astronomy and NSEJS for juniors. IAPT conducts these papers, usually in late November. Qualifiers move to the national Olympiads such as INPhO and INChO, conducted by HBCSE early the next year.
No. Since 2020, the first stage of the Maths Olympiad in India is IOQM, the Indian Olympiad Qualifier in Mathematics, usually held in September. IOQM qualifiers write RMO, the Regional Mathematical Olympiad, and RMO qualifiers go on to INMO, then the IMO Training Camp and finally the International Mathematical Olympiad.
NSEP and NSEC are conducted by the Indian Association of Physics Teachers (IAPT) as stage 1 of the Indian Olympiad programme. Stage 2 onwards — INPhO, INChO, the selection camp and pre-departure training — is run by the Homi Bhabha Centre for Science Education (HBCSE). Check olympiads.hbcse.tifr.res.in for the current cycle.
Olympiad preparation helps with JEE Advanced because both reward multi-concept reasoning over recall. NSEP and INPhO problems train you to build a model before reaching for a formula, which is what JEE Advanced paragraph and multi-correct questions demand. The trade-off is time: Olympiad topics go beyond the JEE syllabus, so plan the overlap deliberately.
Most students start serious Olympiad preparation in Class 9 or 10 for NSEJS, or early in Class 11 for NSEP, NSEC and IOQM. Starting in Class 11 still works if your fundamentals are sound, because stage 1 papers draw heavily on the school syllabus. The first job is fixing weak Class 11 chapters, not collecting hard problems.
BrainStride helps with Olympiad preparation through NSEP, NSEC and IOQM-style reasoning sets, each wrong attempt tagged by the step that failed. Every solution is reviewed by faculty before release. The RankLab plan adds JEE Advanced and Olympiad problem sets, Sunday doubt clinics with faculty and a mentor check-in twice a month.
