Hello Megha,
First of all you should know that in kcet exam both the PUC marks and the kcet marks of Physics, Chemistry and Mathematics plays very important role in achieving a good rank.
For example if you score 70% in PCM in your PUC board exam then you may have to score about 120-130 marks out of 180 marks to get the rank below 5000 but, if you score 85- 90% in your PUC then 90-100 marks in KCET are more than enough to achieve the rank below 5000.
I came to know when one of my friend had got 7000 rank by scoring only 70 marks in kcet but, he scored 89.9% in his PUC exam.
Hope you are satisfied with the answer.
