Application Form

Candidates can register for INO 2018 by logging in with your NSE Centre Code, NSE Roll Number and date of birth. Candidates will be able to choose examination centre for INO during registration. Candidates will be able to log in only if they have qualified for INO 2018. If you are unable to login, it might be due to one of two reasons:

(I) Those candidates who have qualified for INO 2018 can check the list of students selected from the official website. Queries related to login by students not on this list will not be answered.

(II) Some data that you have entered do not match as per records. In this case, please contact to the official authority of INO, providing your name, NSE Centre Code, Roll No. and date of birth.

Eligibility Criteria

To be eligible for the Stage II INO exam leading to the International Olympiad, a candidate must secure a score equal to or greater than a Minimum Admissible Score (MAS). The MAS for a given subject will be 50% of the average of the top ten scores in that subject rounded off to the nearest lower integer.

Merit Index Clause: There will be a high score called the Merit Index (MI) associated with each subject in Olympiads. The MI in a subject is defined as 80% of the average of the top ten scores in that subject rounded off to the nearest lower integer. All students with a score equal to or greater than merit index MI for the subject will automatically qualify for INO Stage II examination in that subject. For example, if the average of top ten scores in a certain subject is 92, then 80% of this is 73.6. Then the MI in that subject will be 73. All candidates with a score equal to or above 73 in that subject will automatically qualify for INO stage II.

Proportional Representation Clause: Students from all States and UTs need to be encouraged to appear for the first stage examination and a nationwide representation for INO Stage II is desirable. The quota for each State/UT used in National Talent Search Examination (NTSE) 2013-14, a nationwide competitive examination will be used as the baseline for calculating the number of students qualifying for Stage II INO in every subject from centres in that State or UT. The target total number of students to be selected in each subject (except Astronomy, see below) is 300. Suppose the NTSE quota is S for a State, and the total for all States and UTs is T, then the total number of students to be selected to INO Stage II from that State would be S/T times 300, rounded off to the nearest higher integer. This number will include those selected on the basis of the Merit Index. In the event of tie at the last position in the list, all students with same marks at this position will qualify to appear for the INO Stage II examination. The selected students must nevertheless satisfy the eligibility clause. The number to be selected from all the centres in each State or UT will be displayed on the IAPT and HBCSE websites

Minimum Representation Clause: Notwithstanding the proportional representation clause the number of students selected for INO from each State and UT must be at least one, provided that the eligibility clause is satisfied.

About the Programme

The programme aims at promoting excellence in science among pre-university students and selecting teams of students to represent India at the International Olympiads in Astronomy, Biology, Chemistry, Junior Science and Physics.

International Olympiad consists of fives stage process as described below.

Stage – I: National Standard Examination (NSE) test with objective type questions and are offered in English and Hindi, with additional languages also available in Physics.

Stage – 2: The best-performing students from the NSEs (approximately 300 in each subject) qualify for the second stage — the Indian National Olympiads (INOs).

Stage – 3: The top students from the INOs (approximately 35 in each subject) are invited for the third stage, the Orientation-cum-Selection Camps (OCSCs) held at HBCSE during April to June.

Stage – 4: The selected Indian teams undergo a rigorous training programme at HBCSE in theory and experiment and in case of astronomy, observational astronomy prior to their departure for the international Olympiads

Stage – 5: The Olympiad programme culminates with the participation of the Indian students (4-6 in each subject) in the International Olympiads.
