Hello Shashank,

KCET follows different ranking systems for engineering and medical ranking. Now that medical entrance is entirely through NEET, I shall answer keeping engineering in mind.

For a rank to be calculated, 50% of your puc or 10+2 marks and 50% of your total CET score is taken into account. After that they start arranging those corrected scores into order of rank list. In cases of ties between scores, the order is based on higher marks in individual subjects in this order of weightage : Physics , Mathematics , and lastly Chemistry. Thus ties are broken and the rank list is prepared.

Now a solid score is not always a good predictor of ranks. You can score above 90% in all and still end up with a 4 digit rank. It all depends on the boards, the CET paper of that day and the scores of the people close to you in the ranklist.

Hence I wound think you should have marks at least 130 to 150 to get a rank under 1000.

Hope this helps.
