Hi,
I don't think with this marks you will be able to get admission into any good or decent college with any category. I will suggest you to drop and re-appear for the examinations the next year.

After the completion of the B.Sc course, you can work in various areas which include both Science & non-Science fields.

For that, you need to score at least 80percentile to get a call from IIMA. For MANAGE, it all depends on cumulative scoring. Yours marks till now are good, and being from Agriculture course, you have high chance of getting a call. Yes, confirming a seat will be easy for those with 80percentile above

There is no admission test to join B.Sc Course in St Xavier's College, the college takes admissions based on your performance in Maths exams in your class 12th Board Exams. You need to have your 10+2 from any recognized board.

The cutoff rank must be below INR. 10k.
