Dear student,

You can get IIT by writing JEE Advanced exam, then by clearing it.

Please note that you can get some other colleges to on the basis of JEE Advanced score.

With this you have to pass JEE Main and 12th exam too from a recognized board.

In case if you have given JEE Main exam and want to predict your rank, then you easily do it by going through the rank predictor tool. Below I am pasting the link for it.

Now when you appear in JEE Advanced, you need to score that much marks that can get you a rank below 10,000. Because for a General student, a rank below 10,000 is must to get any seat in any IIT.

To get a rank under 10,000 you need to score atleast 36% in JEE Advanced paper. There are two papers of JEE Advanced help in a single day and the total marks keep varying each years.
