Should i switch to commerce with maths in class 12th

For start i am an Maharashtra board student

and in 11th i had a subject called Secretarial practices (company law, and corporate stuff) but i later realised that maybe it was a mistake, i am now in 12th, just starting, and i am thinking of switching to maths and calculus since maths comes handy in future

So my question is should i do it or it wouldn't really matter, i am thinking so much since it's class 12th
