To estimate your KCET ranking for the OBC category in 2025, we need to consider the 50:50 weightage given to your board exam marks (PCM) and your KCET marks (PCM).

First, let's calculate your percentage in both:

Board Exam Percentage (PCM): You scored 257 out of 300 in PCM. Percentage = (257 / 300) * 100 = 85.67%

KCET Percentage (PCM): You scored 97 out of 180 in KCET. Percentage = (97 / 180) * 100 = 53.89%

Now, we calculate your CET rank determining score: CET Score = (50% of Board Percentage) + (50% of KCET Percentage) CET Score = (0.50 * 85.67) + (0.50 * 53.89) CET Score = 42.835 + 26.945 CET Score = 69.78

Based on the previous year's trends and the relationship between KCET scores and ranks, a CET score around 70 generally corresponds to a rank somewhere in the range of 40,001 to 50,000 or even higher .

However, since you belong to the OBC category (specifically 2A or 2B, as 3A and 3B are also OBC sub-categories in Karnataka), your rank within the OBC category will be better than your general rank. The exact OBC rank depends on the number of candidates in each category and their respective scores.

To get a more precise idea of your OBC rank, you would need to wait for the official KCET results, which will provide both your general rank and your category-specific rank. You can also look at the previous year's cutoff ranks for OBC categories in different engineering colleges to understand the rank range for admissions. Keep in mind that cutoffs can vary slightly each year.

Therefore, while your estimated general rank is in the higher range, your OBC category rank will be better, potentially improving your chances of getting a seat in some engineering colleges. It is important to check the official KCET results and category-wise cutoff ranks once they are released.

I hope it helps.
