Hello Rinkesh, to help you I am attaching a link that will predict the branch and the college that you can get based on your performance in this exam. https://www.shiksha.com/engineering/jee-main-college-predictor

Hello Sandeep, while calculating percentile, certain data is required. Unfortunately this data is available only with NTA. Hence it's almost impossible to find out percentile for any one else. I would like to advise you to not worry on this part. But surely NTA informs students about their percentile while declaring results. Just wait few days for the results to be declared. Best wishes to you.

Hello Kim, deemed to be universities have their own method of giving admission to probable students. They invariably conduct their own entrance exam and then give admissions based on the performance in this examination. A student is of course supposed to keep track of this admission process. For private engineering colleges, associated with different universities in different states, they follow the pattern prescribed by their concerned states. However, the management quota seats are filled directly by these colleges. Best wishes to you.
