Hi Reshma,
After class 12th, you can directly try for BBA or BBM.

As long as you are technically strong, you won't face any issues. So, I would recommend you to learn the language practically by joining some course and enhance your technical skills. Employer is more concerned about your technical part, and if you are able to impress him in the same, you will be hired.

Hi,
As per your interest in entrepreneurship, you should watch Shark Tank and The Vault online series that give you knowledge about the entrepreneurship skills and foundation. Even you can watch TED talk.
To set a business, there is no specific degree required. But, you can consider BBA program as you would get the knowledge related to marketing strategy, business management, finance management, etc.
All the best.
