Hello Amey,

You will have to work very hard to get a seat in CS in IIT Mains and Advance. Getting into an IIT requires getting a GOOD RANK in JEE Advanced only. You can get a seat in CS if your score is around 130 in JEE advance for genral category. You will have to work very hard to achieve your dreams because it is one of the most tough and unpredictable paper. To get a seat in good IIT you must have rank in three digit.

All the best !!

Thank you
