JEE Preparation

prepare your 11 and 12 sllaybus .

To become astronaut you will have to become a Pilot or Flight Engineer. Opportunities to become Astronaut are very few ( you can count them on fingers). In India astronauts were inducted from Fighter branch of Indian Air Force. I will recommend that complete Aeronautical Engineering degree and learn to fly. You can then apply to organisations such as NASA to fulfill your dream.

when we prepare for JEE we also get prepared for all other entrance exams. so you get prepared for NID by JEE
