Dear aspirant,
The cutoff fluctuates every year by a percent or two. It depends on the stream or course you want to choose. But generally for the general category one should score 80+ % in order to get admission in the Fergusson College. Reserved category students (SC, ST, OBC, NT, SBC) can get admission on 70+ %.You can gain benefit of caste category only if you have caste certificate and a resident of Maharashtra state for the past 15 years.
Hope it helps,thank you.
