With a KCET score of 123 and a PCB score of 281, and belonging to the OBC 2A category, securing a veterinary college seat in Karnataka is a possibility. However, getting a seat specifically at the Veterinary College in Hebbal might be competitive.

Based on previous year's KCET cutoff trends, the closing ranks for veterinary colleges, including the one in Hebbal, tend to be quite high. For the general merit category, the ranks often fall within the top few thousand. While reservation for the OBC 2A category does provide an advantage, the competition for the limited number of seats, especially in a preferred college like Hebbal, remains significant.

Your PCB score of 281 is a crucial factor for veterinary admissions in Karnataka. Typically, a good PCB score is highly valued for securing a seat. While your KCET score is also considered, the PCB score often carries more weight for veterinary admissions.

To assess your chances for the Veterinary College in Hebbal, it's essential to refer to the official KCET cutoff ranks from the previous years specifically for the OBC 2A category. These cutoffs are released by the Karnataka Examinations Authority (KEA) after each round of counselling. You should also check if there are any specific category-wise seat allocations for OBC 2A candidates at the Hebbal college.

While getting a seat in Hebbal might be challenging, you should also explore other veterinary colleges in Karnataka. There are other reputable colleges where your OBC 2A category and PCB score might give you a better chance. Keep an eye on the KEA counselling schedule and the seat matrix released for each round. Applying to multiple colleges and understanding the category-wise cutoffs will help you make informed choices during the counselling process and maximize your chances of getting a veterinary seat in Karnataka.
