Hello Urmila,

To keep yourself in a safer zone, you must score at least 60% score in KCET (PCB). For one marks your rank may vary from 1.5K to 2k . So you have to score 130+ in the CET paper, If you are from general. If you have any other good reservation then may be you will get veterinary  government seat for around 100+ marks.
