see cutoff score changes every year and it depends on certain factors like number of applicants, questions difficulty level, seat matrix, students category etc. there is various different 3B category like 3b general, 3BH, 3BK, 3BKH, 3BR, ETC. however considering you as 3b general you have no chances in any colleges for bsc agriculture score as per previous years cutoff.
