Elementary Astronomical notions:

Basic knowledge of Solar System and associated phenomena: Sun, Planets and their moons, Comets, Asteroids, Diurnal motion of Earth, Phases of the Moon, Seasons, Eclipses, Tides.

Familiarity with structural elements of the Universe: Stars, Galaxies, Clusters of galaxies.

Familiarity with the night sky: Brightest stars, Common constellations, Milky Way, paths of solar system objects in the night sky, rising and setting of stars.

Working principle of Telescopes.

Major historical landmarks in development of Astronomy. Any in-depth knowledge of astronomy is not required. However, basic familiarity with astronomical terminology, objects and phenomena, as can be acquired through an interest in astronomy (reading popular books / listening to popular lectures etc.) is expected.

Preparation Tips for NSEA-

Be clear with the basics-

You need to have a very good hold on your basics. If you have a good foundation, you can solve advanced level questions without much difficulty.

Try to dig deeper in the concepts-

Completing your syllabus even after revising won’t give you good results. Hence, you need to dig deeper so you may have a broader vision and can solve any problem without any difficulty.

Manage your time-

A student’s rank can fluctuate by even a single mark. Try to practice your questions in a particular time frame with high accuracy.

Choose your study material wisely-

Choose the study material (online or offline) which has some advanced problems to solve so that they can acquaint you to the level of competition you are going to face.

Take mock tests –

Practicing at home is very effective if you do it regularly. Take mock tests to have an idea about the pattern of the exam, but do not forget to review the mock tests. Usually, the students make a mistake by not reviewing their mock tests. Try to analyze the questions you are facing a problem with and the areas you need to solve. Work on your weaknesses.

High Accuracy-

Just practicing the question will not help you much. You have to practice them in a given time frame with high accuracy. The more you practice, the more you will be able to reduce your mistakes and higher the accuracy.
