No, minimum percentage requirement is only clearing mark sheets of class 10th and class 12th.

Yes, you can get, but for the good college, you have to wait till the spot round or the last round of counselling.

If you are talking about getting admission in MBA, you have to take the necessary exams, /tests in the colleges you prefer. Different institutes have different exams such as CAT XAT MAH-CET. Anyone from any stream can pursue MBA. I hope, you are not talking about getting admission in some particular university/ institute.

Yes, you can. You will find some aspects of the course easier and tougher than a science student. Accountancy is one subject you will have an advantage over science students and it is an important subject for the course. But there are also certain subjects such as food science and nutrition, that you may find difficult than a science student, but they are minor subjects and not as major as accountancy, which will be a subject that would be present for the entire course most probably.
