KCET rank is calculated considering 50% of KCET score and 50% of board marks. Now it is difficult to figure out any particular rank as it depends on few factors like no. Of candidates appeared, highest marks obtained etc. And these factors keep changing every year. You have good percentage in 12th, but KCET marks are not so impressive. Now if we see last year's data, your expected rank will be 45,000 to 50,000 approximately.
