Last year, the highest cutoff for bsc(h) statistics was 99.75% in lady Sri ram college and 99.25 in hindu college and lowest was 92% in mata sundari college for women (in the first cutoff list). Some college had 97% also, so there are quite nice chances that you could get admission in an average college in DU with the percentage of yours if internals are considered for evaluations.

All the best!
