Eligibility Criteria

School-enrolled contestants

If you are enrolled in school, then the category for which you are eligible is determined by the grade in which you are studying. If you are studying in grade 6, 7, or 8, you are eligible to appear for the Junior contest. If you are studying in grade 9, 10, 11, or 12, you are eligible to appear for the Senior contest. However, if you have attended the Invitational Round Camp in any previous year, you can appear only in the Senior contest.

You must carry an official school photo ID that states your name, school name, and grade in which you are studying (or date of birth), and has a photograph of you.

Contestants not enrolled in school

If you are not enrolled in school, your category will be decided by the equivalent grade that you would otherwise belong to. If you have attended the Invitational Round Camp in any previous year, you can appear only in the Senior contest.

You must carry a government issued photo ID (Aadhaar card, passport, etc.) that states your name, and date of birth, and has a photograph of you.

Other rules

• Eligible contestants who have represented India at the IOL in the past are qualified for direct entry to the Invitational Round camp, and need not appear for the Round 1 contest.
• Contestants who are not citizens of India are eligible to participate in the Round 1 contest provided they reside in India and are enrolled in a school in India.
• Contestants who have begun university are not eligible to register for PLO.
• Contestants who are aged 20 or older on the day of the IOL are not eligible to register for PLO.

Important points

If you could not register for PLO in time, you can also register yourself at the nearest centre on the exam day, as a "walk-in" applicant: share your registration details and pay the standard registration fee for that year at the centre itself.

Once the registrations get done, a tentative list of students and their roll numbers will be posted on the website itself, keep checking the website for further updates!
