what will be my KCET rank if my boards PCM % is 85 and KCET score is 130+ ?

Hello there,
KCET rank cannot be predicted accurately as it depends on factors like difficulty of the paper, and the no.of students appearing for it. Also, as you know KCET takes into consideration both your board marks and your KCET marks, hence it is very difficult to predict your rank.
Now, analysing your marks, we see that,
50% of 85% comes from your Boards, which is, 42.5%.
And, 130 (suppose) comes from your KCET, which is -
(130/180*100)% = 72.2%,
50% of 72.2% is 36.1%.
Total percentile= 36.1+42.5 = 78.6%
For total percentile around 85, you can get a rank below or equal to 1000.
So, for your total percentile, you can expect a rank around 1500-2500 approximately.

Hope this answer helps.
Good luck!!
