Hello Aspirant

It's really good to hear that you are very clear about your future goals, it really makes you one level up on other students.

If we talk about banking sector, than you must do your class 12th in commerce with maths.

After doing class 12, you can do bcom or bcom hons because these two courses are more related to finance sector.

There's no compulsion for choosing these two as anyone can get a job in banks even if they are from arts or science side too, but doing these two courses will give you an edge over others.

Also you can try for competitive exams like Bank PO for government banking jobs or for private you have to apply in banks where ever vaccines are out and after that you have to appear in interview.
