hello aspirant,

your kcet exam depends on both pu and kcet marks you have to perform well in both the exams to get rank below 1000 ,and 75%of kcet marks and 25% of pu marks be calculated so you have to score maximum 150/180 marks to get below 1000 rank.

all the best

thank you.

Hello.

KCET rankings are based on your performance in both board exams(PCM) as well as in the KCET. For better rankings, try to score as much as possible in the board exams as it can help a lot to increase your chances of getting a better rank than other students. Regarding KCET, a score of atleast 145/180 is necessary due to high competition. 

Good luck!
