Hi

Your profile suggests that your home state is Telangana

It's quite difficult to predict because cutoff keeps changing every year depending upon various factors like :-

******number of students that appeared in the  jee main exam,

****** number of available seats,

****** performance of different students in the examination,

****** the category you belong etc.

But yes,

When we go through previous year trend then

>>>>> with  15k st rank

You have low chance in NITs .

For example,

Under other state quota , closing rank for some of the lower nits for which closing rank goes low are listed below along with their closing rank in the 6th round of josaa counselling 2020 for st category  :-

• NIT Mizoram ,civil engineering :-   2975 st rank

• Nit nagaland ,Electronics and Instrumentation Engineering :- 3086 st rank

• National Institute of Technology Agartala,    Biotechnology and Biochemical Engineering:- 3521 st rank

You can check the same at

From above, it is clear that you need at least a rank of around 3500 st rank to get into an NIT .
