To estimate your KCET rank, we need to consider both your KCET score (66 out of 180) and your board exam marks (280 out of 300). The Karnataka Examinations Authority (KEA) gives equal weightage (50%) to both these scores to determine your CET score, which is then used to assign the rank.

Here's how to calculate your estimated CET score:

1. Calculate your board exam percentage in PCM: Assuming the 280 out of 300 is the total of your marks in Physics, Chemistry, and Mathematics, your percentage in PCM is: (280 / 300) * 100 = 93.33% (approximately)

2. Calculate your KCET percentage: Your KCET score is 66 out of 180. Percentage = (66 / 180) * 100 = 36.67% (approximately)

3. Calculate your CET score: CET Score = (50% of Board Percentage) + (50% of KCET Percentage) CET Score = (0.50 * 93.33) + (0.50 * 36.67) CET Score = 46.665 + 18.335 CET Score = 65

Now, to estimate your rank based on this CET score, we need to look at previous years' trends of KCET marks vs. rank. Keep in mind that these trends can vary slightly each year.

Based on the previous year's data and available rank predictors, a CET score around 65 could potentially place you in the rank range of approximately 40,001 to 60,000 .

I hope this helps.
