Dear applicant, if you get both of them during counselling, then decide which one you wish to opt. If Pharmacy counselling is the first one, then follow their information brochure to get the information regarding how to sit for the BAMS counselling. In genuine cases if you don't sit for the first counseling, you can sit in the subsequent counselling as the first one would be rejected and you need to upgrade your choice and in 2nd round fix the choice you got. Then also check the information brochure of KCET, give it a read and sit for BAMS counselling

Good luck!!
