hello aspirant,
77 would fetch you a rank 235290-264500 .now these are based on previous year analysis .As of now its tough to say because the analysis and also cutoffs change every year due to many factors like total students appearing for exam,difficulty level of paper etc.as you did not mention your category considering you from general category now based on your rank you and last year round 6 closing ranks will have tough to tough to no chances to fetch seat .you need a percentile of 96-98+ to fetch seat in nits or iiits. work hard and improve your score in the upcoming jee main sessions.for more information refer to: https://engineering.careers360.com/jee-main-college-predictor?icn=QnA&ici=qna_answer
