KCET rank will be calculated by considering the performances in KCET and QE (qualifying examination) as well.I will explain with an example ,let us assume that u have scored 131/180 in KCET and 288/300 in QE,then your % marks in KCET is 72.77% and in QE it is 96% now they will add this two( that is, the formula goes like this

Rank will be given

R={(%KCET+%QE)/200}×100

Then they will sort ,who has got more R(i have taken this ‘R’ for better understanding) value will get good rank.

And the rank to a particular ‘R’ value varies every year
