Hello,

Whole mark will be considered i.e.300 (Physics,Chemistry,mathematics) . There is no partial consideration like thoery and lab marks.  They will consider total marks and it holds 50% to the total score in KCET and rest 50% is score from the entrance exam.

That score will determine your final rank under general category. if you have any reservation then the board will decide by which factor your rank will get divided.

Hope it help!
