At 86.45 percentile and secondly since you have the OBC-NCL Advantage, I believe you might just be able to secure a seat in either of Mining, Metallurgical, Civil or Chemical Engineering a BIT Sindri. Of the above 4, Mining and Metallurgical branches have  comparatively better career prospects at the institute, since Sindri being located in a Mineral Rich Region, with huge conglomerates like Coal India , Tata Steel and Vedanta operating their Mines and Plants from Jharkhand and Odisha. All the best.
