Quick Details

-:About the competition:- is one of the fastest growing physics and science websites on the internet. We set out with the goal of providing simple and short explanations to some of the most complex ideas in physics. Our next goal was to directly engage people in solving, learning and developing an interest in physics. This is what we wish to achieve with AIAPC.

After the success of the first AIAPC in 2020, is hosting the Annual International Astronomy and Physics Competition for a second time, in 2021. The competition aims at testing and developing knowledge and interest in physics/astronomy among the general populace. The competition will be challenging as well as fun at the same time. The solutions/explanations for each problem will be released after the competition is completed, allowing participants to learn from their mistakes or learn something completely new!

1. How will participants be ranked?

Participants will be ranked by their “final score” which will be the sum of scores from Quali and Advanced Round

2. What if two people score the same?

If two people score the same, the person with higher score in either Quali/Advanced Round ranks higher. If they are the same, the person with lower education level ranks higher. If those are the same, then the younger participant ranks higher. Even if age is same, the person who submits advanced round paper sooner will rank higher.

3. Where will we get our certificates?

You will get your certificate on your registered email ID.
