Score or percentile may vary from year to year as it changes since it depends on various factors like number of candidates appearing and also the paper level difficulty, etc. So I'll guide you with the ranks for CS stream. So last year, students having rank upto 9203 in JEE MAINS got an admission into CS branch into BITS MESRA RANCHI. You need to score around 180-190 marks in jee mains 2018 to get cse branch in BIT MESRA for others state candidates and for home state candidates 170-180 in jee mains will be enough to get cse branch in BIT MESRA.

Refer to the site below to know the exact rank wise cutoffs of all the streams in BITS MESRA college..
