Sir/Ma'am, Birsa Institute of Technology Sindri, college provides admission only through the JCECE(Jharkhand Combined Entrance Competitive Examination) conducted by JCECE board constituted by the government of Jharkhand. Hence I don't think the JEE mains percentile will get you admission in this college. But considering your fine Percentile, and reservation status, you may get admission in other colleges of Jharkhand, which consider JEE mains score. JEE MAINS is a national examination, so most colleges do consider the score. Otherwise you can try and apply for BIT Sindri using your JCECE score. JCECE being the centralised exam in Jharkhand may get you admission in other top colleges of Jharkhand too, depending on your score.
