Hi ! There are very few IIT where you can get the course of engineering physics. These IIT's are top level IIT's. To get admission in these IIT's with your concerned course you must have rank between 2000 which is maximum. The 2nd tier and third tier IIT's doesn't have this course or instead very few. So hope you understand and best of luck to you.
