Hello Yogesh, I am afraid 120 marks in JEE Advanced are rather low for getting admission in an IIT.

You will surely get an IIT so don't worry about that. Girls are given a special quota, so you will get. But it depends if your score is better than others or not. Keep on trying.
All the best.

This is the college predictor link. Here, you will get that what college you will get.

We can't predict the rank from the marks, rank is one of the main aspect rather than marks. It totally depends on the number of students applied and how they perform. It is very difficult to predict the rank before the result.

For that you have to score under 300 AIR. Only then, you can be able to get this course, as CS is the main branch and student's first preference is this only.
