No, you cannot appear for the Indian Council of Agricultural Research exam(ICAR), until you complete your class 12 from CBSE, or any equivalent from a recognized Indian board or University.
If you fall under general, OBC,UPS categories, then you should get atleast 50% aggregate marks in 12th.
If you fall under SC,ST,PC categories, then you should get atleast 40% aggregate marks in your 12th.
