Hi Dear,

As you have mentioned that you are from commerce background so you'll not get course involving core mathematics. However, since you are interested in Mathematics you can go for undergraduate courses in Statistics, economics or you can go for Actuarial Science or CA/CMA. Also, you can go for BCA or digital marketing course as per your interest in computer.
