There are many fields like BCA or you can also go for BSc in computers or BSc in mathematics. Or you can simply go for Bcom however this doesn't involve computers. There are plenty of options for you but if you tell me about your interest or any particular course I can guide you better.
Hope it helps.
Thank you.

Hi Shreya,

You can go for the research field ie; you can start pursuing research fellowships in computational mathematics which are used for our safety across borders, you can go for research in anyone field also like either maths or computer. You can start your coaching classes. You can even go for lectureship in any of the fields by completing your PhD.
