Read more about IOQ 2020-21.

The National level NSEA Olympiad is conducted each year by the nationally recognized Indian Association of Physics Teachers (IAPT). The organization is also well known to organize various other Olympiad competitions in the field of Science like NSEC, NSEP, and NSEB.

Importance of NSEA For Class 12 Students

The National Standard Examination in Astronomy or NSEA is a front runner Olympiad in the field of evaluating the students up to their utmost potential. The syllabus of NSEA is mainly organized in a way that enables polishing the prodigies of students based on their basic education level. The NSEA 2020 exam is likely to take place in November. Until now, the official dates of the national level examination are confirmed for the Last week of November. However, for any changes in any related important events due to a pandemic situation in the country, we will duly update on the same for the convenience of the student.

As per the IAPT, the NSEA Syllabus 2020 is typically based upon the syllabus of the CBSE board of the class 12th. That makes it utterly important for the participating students to consider the workbooks prescribed by the NCERT for the preparations of the NSEA 2020. Keep in mind that the majority of questions in the NSEA exam paper comes from the sciences section of Physics, Chemistry, Biology, And Maths in comparison to elementary Astronomy. Check below for the comprehensive list of subjects and topics that will be covered in the NSEA question paper 2020.

FAQ (Frequently Asked Questions)

Q1. What will be NSEA 2020 Best Preparation Tips?

Ans: To perform excellently and excel in the NSEA exam 2020, one must be thorough and thoughtful ahead of the competition. Participating students must enroll for an online master who is proficient enough to not only help with academic subjects but also makes for hands-down preparation for the NSEA Olympiad 2020. Vedantu is a cut above the rest in terms of imparting knowledge and set the basics clear that holds all the importance. Also, check for NSEA Question Papers, previous year question papers, NCERT recommended activity books, and e-quiz.

Q2. What is the NSEA 2020 Exam Pattern?

Ans: Remember, the IAPT organized NSEA Olympiad 2020 Exam Pattern is just not similar to the CBSE. Though the IAPT NSEA 2020 is quite as unique as one of the boards and that the conducting body runs parallel to CBSE syllabus. But make no mistake, students as the marking scheme of the NSEA Exam Pattern is just not similar to that of the CBSE. NSEA 2020 question paper will have 80 Multiple Choice Questions (MCQs). The NSEA exam also has Negative Marking. The NSEA question paper will be available both in English & Hindi. Thus, applicants have the liberty to choose their optional language at the time of registration.

Q3. What Type of Questions Comes From Conic Sections of Mathematics?

Ans: Two hypothetical planets in the form of ellipses namely M and N of the same size have apparent magnitudes of - 7.5 and 2.5 and real magnitudes of 4.5 and -1.5 respectively. We draw an inference that:

i.) M is much closer and hotter to earth than N.

ii.) N is much closer and hotter to earth than M.

iii.) M is much hotter than N and N is much closer to earth than M.

iv.) N is much hotter than M and M is much closer to earth than N.

Q4. Please Mention the Physics Questions From NSEA Previous Year Question Paper?

Ans: One type of question that came in NSEA 2019 question paper included:

Besides the planet earth, Aurora phenomena are noticed on which of the following planet:

i.) Mercury

ii.) Venus

iii.) Mars
