Hello Aspirant,

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 . If you have any other good reservation then may be you will get veterinary  government seat for around 100+ marks. For the marks you have mentioned it is just difficult you to get veterinary college, But don't lose hope because KCET cut-off changes every year based on different factors like students appeared for exam etc.
