Indian citizens who are in classes 9th, 10th, 11th, 12th at the time of examination are eligible to write the exam.
Format
The paper consists of both single correct type and multiple correct type questions. There are questions from high school level physics, mathematics and some questions from general astronomy.
Question Paper
The medium of test is English only and comprises 70 objective questions. 60 questions are single correct type and have marking scheme of 3,0,-1. 10 questions are multiple correct type and the marking scheme is 6,0,0.
The basic objective of conducting this test is not focusing on merit but to involve as many students from the country to participate in the exam and try to show and expose their talent. Hence the selection to the stage II examinations i.e. Indian National Olympiad Examinations is based on the following scheme.
Cutoff
To be eligible to get to the next level, i.e. the second stage, it is necessary that a student scores at-least a Minimum Admissible Score which is 50% of the average marks scored by top 10 candidates.
The maximum number of students that can get to Stage II in each subject is around 300. These many students are not selected only on the merit basis but also on proportionate basis. This proportion is decided on the base of the number of candidates who appeared for NSE in the previous year from that center in each State or Union Territory. In case there is a tie at the last position, then all the students competing for the last position will be eligible to move to stage II. However it’s necessary that the selected students fulfill the eligibility clause laid out above. The total number to be selected from centers in each State for each subject will be displayed on the IAPT and HBCSE website.
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.
Merit Clause
As stated above, approximately 300 students are to be selected for second stage. If this does not happen according to MAS, then after selection as per merit, the shortfall from 300 students will be selected based purely on merit without further consideration to proportional representation and minimum representation clauses. In the event of a tie at the last position in the list all students with the same marks at this position will qualify to appear for the Stage II examination.
Fee
The fee for the NSEA is about Rs. 150. Application for this examination is typically handled through the school/college to which the student is affiliate
Indian National Astronomy Olympiad
Held in first week of February, this is a subjective exam. Students are divided into two pools; A, with those in class 12, and B, with those in class 11 or below. Top 15 students from group A and top 35 students from group B are selected for the third stage.
OCSC Astronomy
The students are taught and tested on data analysis, theory and observation. From their performance in the tests, a team of five students is selected to represent India in IOAA.
