Hello Diksha,
GGDSD College has a high cut-off for Bachelor Of Commerce Hons which has been increasing overtime due to increased competition. Although precise numbers aren’t available because they change every year. In 2014 when I joined the college it was around 93% for general category and it declines if there are multiple rounds of counseling. It goes down to around 88% for the last round of counseling. Plus Mathematics as a subject in 12th standard give additional advantage. The lowest I have seen is 62%, one of my batch mates from SC category had it.
A score of around 92% + with mathematics would be a safe bet for 2018–2021 batch even.
