All the best.

If you want to get a admission in any IIT then you will have to pass the JEE ADVANCED examination with good ranks.

Now to be eligible for JEE ADVANCED you need to be in the top 2,50,000 of the JEE MAINS,2021.

Sorry to say with the percentile you have mentioned, you can expect an rank between 440504 - 495190 which will not make you eligible for JEE ADVANCED'2021.

Now you can improve your score if you attempt the remaining sessions of JEE MAINS,2021.
