Hello Bharti,
Yeah. First of the most basic math is needed each and everywhere in life. And when coming to advanced maths like integration and all. They are mostly only useful in CPT and somewhat in final. Being strong at maths is surely gonna help you in costing and financial management as well as accounts.
Maths may not be as much needed when you pursue your CA course but once when you are done with CA and you want to join some field like investment banking, stock market, portfolio manager, financial analyst,etc you will understand the dire importance of advanced maths. Many leave up maths in CPT thinking that the other subjects will set off it.
