Then you need to clear the JEE Mains examination with good rank and get qualified for JEE Advanced. Now the important and the hardest thing is to clear the JEE Advanced examination with a good rank. Once you have done this, no one can stop you from getting a seat in IIT, that to in your desired branch. The more percentage you get in class 12 and the better rank you secure in JEE Advanced, the more will be your chances to get into IIT. I hope you will understand after reading this answer.
