Hi Kavya!
As you have completed your class 10th through Tamil Nadu State Board. Don't worry. You are definitely eligible to apply for the Diploma in agriculture. Just prepare for Diploma exam. Best of luck.

Never heard of it. Get familiar about top colleges by going through reputed B school ranking. I used to follow TIME B-School ranking, career launcher ranking is also fine. Check out Shiksha's ranking also you will get a clear picture then.
