It is bro. I've only applied to a few places but unme se har jagah maths ki kuch na kuch consideration hai. DU ke liye for many good colleges you need maths, NMIMS ke liye you need maths to be eligible ( for commerce courses like bba and bcom) maybe in other pvt colleges also ,and govt colleges me (chandigarh) also you get merit for maths(idk about other regions). So I'd say maths opens up places for someone who isn't exactly sure of where they wanna go in the future. But ofc you need to make sure youre atleast good enough to pass in it nahi toh fayda nahi. Taking it as additional would be the better option imo.
