FAQ (Frequently Asked Questions)

Question 1) What is the Cutoff for the Second Stage?

Answer) If the student wants to be eligible to get to the next level, that is the second stage, it is necessary that a student scores at-least a Minimum Admissible Score (MAS) which is equal to 40% of the maximum score.

Question 2) What is the Eligibility Criteria for NSEA?

Answer) The student must himself ensure that he fulfills each criterion of NSEA Eligibility Criteria. At any stage, if the student is found not eligible, he/she will be immediately forbidden from the examination. The eligibility criteria are as follows:

  • The student must be eligible to hold an Indian passport.

  • The Date of birth of the student between 1st July 2001 and June 30th, 2006 both days inclusive.

  • The student must be residing and studying in India since November 30, 2018, or earlier OR must be studying in an Indian school system since November 30, the year 2018, or earlier OR the student must be studying in an Indian school system since November 30, 2018, or earlier.

  • Should not have passed (or scheduled to complete) class XII board examination or equivalent earlier than November 30, 2020.

  • Should not have commenced (or planning to commence) studies in a university or equivalent institution by June 1, 2021.

  • Should not be appearing for any NSEJS 2020.

Question 3) What Topics Should I Focus on as I Prepare for NSEA?


  • Thorough knowledge of mathematics is necessary, and expect one purely mathematical question in the NSEA Exam.

  • All topics of physics mentioned for NSEA are important with thorough and complete knowledge. Just because NSEA is an astronomy Olympiad doesn't mean it will ask questions only related to astronomy. 

  • The questions in NSEA are highly calculation based. Almost 10 questions will involve just mathematical calculations. 

  • Probability is important. 

  • The next most important topic: Gravitation. Expect all kinds of questions from here. 

  • Optics can also be expected since telescopes and optical instruments are important to astronomy. Mechanics (Newton's laws, kinematics, the centre of mass, work energy power, collisions, rigid body dynamics, relativity in order of the importance), Thermodynamics, Heat transfer (especially the topic radiation), Waves and Electromagnetism.

  • Rigid body dynamics, it seems, does not have that much weightage. 

  • The questions are not difficult but are time-consuming with lengthy calculations. Be prepared. 

  • Calculations are what make NSEA different from NSEP. Hardly any question from pure astronomy is asked.

Question 4) What is the Syllabus for the NSEA Exam?

Answer)The syllabus for National Standard Examination in Astronomy (NSEA) is almost similar to the curriculum of senior secondary level (Class XI and Class XII) of CBSE.  No detailed syllabus is given for NSEA. There is a greater emphasis on physics and mathematics (calculus not asked) and elementary astronomy.
