To estimate your rank for the BNYS (Bachelor of Naturopathy and Yogic Sciences) course with 78% in PCB in PUC and 33.33% in KCET PCB, we need to consider the 50:50 weightage given to both scores for KCET ranking.

First, let's calculate your weighted scores:

• PUC (PCB) Weighted Score: 50% of 78% = 0.50 * 78 = 39
• KCET (PCB) Weighted Score: 50% of 33.33% = 0.50 * 33.33 = 16.665

Now, add these weighted scores to get your CET score:

CET Score = PUC Weighted Score + KCET Weighted Score CET Score = 39 + 16.665 = 55.665

Based on previous years' trends, a KCET score around 55-56 might correspond to a relatively high rank. Ranks can vary each year, but this score is likely to place you somewhere above 50,000 and potentially beyond 70,000 or even higher .

Regarding your chances of getting a government BNYS seat under the OBC 2A category, admission to government colleges for BNYS is usually through KCET, and it is competitive. The cutoff ranks for government BNYS colleges for the OBC 2A category typically fall within a much better rank range than what your estimated score suggests.

Looking at past data, the closing ranks for government BNYS colleges for all categories have generally been within the range of a few thousand to around 10,000. With your current estimated score and potential rank, securing a seat in a government BNYS college might be difficult.

However, it is crucial to check the official KCET cutoff ranks released by the Karnataka Examinations Authority (KEA) after the results are announced and during the counseling process. These official cutoffs will give you the most accurate information about your chances for each college and category. You should also explore private BNYS colleges, as their admission criteria and cutoffs might be different.

I hope this helps.
