Dear Kavitha!!

With just qualifying percentile you will not be able to get NIT Warangal as this one of the top NIT's so cut off's are very high also you can check previous years cut off's of all NIT's , IIIT's and GFTI's  with the link :

Hope this will help you to gey your desired college and for further queries you can comment below

Thank You.

Sorry. But you cannot take a dual degree program with just qualifying percentile at NIT WARANGAL.  As you know, this NIT comes under top 5 NITs . So even for dual degree programs their cut off is much more higher than other NITs although the dual program has lesser cut off with respect to the 4year program.
