Fergusson College cutoff stays in the range of 55% - 95%. The required cutoff will depend on various factors such as branch, category, domicile, and competition. For reserved category students, the cutoff is usually lower. Each year, Fergusson publishes multiple merit lists depending on the number of seats available and vacant seats.
Well, the college releases cut-off scores for 3 boards separately for the process of admission. This answer is based on the cutoff score a few years back when my friend opted for a course at Fergusson College.
The three boards for which the cut-off scores are released are as follows: ISC - Indian School Certificate, CBSE - Central Board for Secondary Education and Maharashtra Board.
The usual cut-off score as per official data would range somewhere around the above-mentioned data. For more information regarding this, you can refer to the official website of the college or visit a few online portals.
