Can u suggest me one or two years course in banking by which i can earn nearly 50,000?

If you have got 85% percent marks or 3.6GPA overall in your graduation, then you can be able to earn this much salary, and that is not enough, you must have a sound knowledge in your area of interest

If you are otherwise qualified for banking jobs then get good coaching and excel in the banking PO exam which can give you a job of above amount in any bank.
