can we get admission in JJ college of architecture with jee percentile 90.3( general)

Hello there,
According to the rank formula, [100-90.3*112679/100], your All India Rank is 10929, where 112679 is the number of candidates who appeared for JEE Main paper 2.  With this rank, there are little chances for you to get admission into Sir JJ College of Architecture. But you can give it a try, since the cutoff ranks change every year depending on the difficulty of the paper, and the number of candidates appearing for it.
Hope this answer helps you.
Good luck!!
