Hello! Congratulations on scoring 84% in JEE Main.

Admission to top engineering colleges like IITs, NITs, and IIITs depends mainly on your All India Rank (AIR) in JEE Main or JEE Advanced, not just the percentage score. With 84%, you have a good chance of getting admission in some NITs, IIITs, or GFTIs, depending on your category, home state quota, and cutoff trends for the year. However, IIT admissions usually require a higher rank from JEE Advanced.

To get a clearer idea of the colleges and branches you can get, you can use the JEE Main College Predictor tool on Careers360 by entering your score and category.
