Hello,
There is no fixed number to get admission in Navodaya . Selection depends on the cut-off marks, which change every year.
Cut-off marks are different for categories like General, OBC, SC, ST and also depend on the number of seats available.
To be safe, you should try to score as high as possible.
Hope it helps !
