Hi Kiran,
I don't think it will be possible for you to get NIT Surathkal by JoSSA counseling because you need to secure a rank below 10000 to stand a chance in any branch.
Competition is such that even after the 7th round of JoSSA, it will not be possible for you because the cutoff does not go above 15000.
All the best!!!
