Class 12-Commerce

Because I'm unsure what exactly your definition of bright future is, I would suggest you do some research to narrow down the field you want to work in. IT, e-commerce, marketing, and finance are all viable options for you. Also, take a look at jobs that have become more popular in India in the last few years. You should also consider if entrepreneurship is a possibility in your future.
In some fields (real estate, web development, computer support, etc.), it is possible that you don't need a degree to pursue a particular career and a certification/diploma will suffice.
Consider universities, such as AIMS Institutes that offer a wide range of programmes. It is a management college in Bangalore but also offers pre university courses, humanities and culinary arts degrees along with business and commerce degrees. Researching such universities will give you some ideas and help you eventually choose a course that will qualify you for an in-demand job with plenty of opportunities.
I hope this will help you.
