Class 11

You must study hard to be an astronaut. You must master in mathematics and physics, and also other subject. By the time India plans to send astronauts on mars, you can prepare very well.

Since, you did not mention what exactly you want to study, it will be difficult to guide you properly. Entrance exams accordingly will vary with your program choice. Please refer to the link provided for all the details.

JEE exam has two language options English and Hindi, so you will also have Hindi paper for JEE but would recommend you to start learning English because none of the institutes teaches in Hindi.
