JEE Advanced Scores

280 is a decent score. State your AIR or use Shiksha college predictor service.

As you told that you have interest in every field I think you are an all-rounder. Jokes apart, all these courses are professional courses. You can't do this and that, and my best opinion is that choose as per your interest. And choose wisely. At this rank and mark, you can't get IIT.

This year, IITs will have at least 14% of girls. If the number of girls through regular counselling will be less than 14%, then IIT will increase the no. of seats for a girl. But, it is the matter of chance. So, considering no special reservation for girls, I think you will get some moderate IITs, such as Gandhinagar and Mandi.

By going with the rank vs mark list or previous years JEE Advanced, your JEE Advanced rank will be around 15-20k.

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.
