hey aspirant,

qualification for kcet is that aperson should have passed PUC , +2 or anyother equivalence from science streame,with physicas and mathamatics as compulsary subjects and one other optional subject like chemistry, biology,electronics , computer science etc.

so if you have cleared your puc in science streame with 64 percentage you can definetly write kcet.

hope this helps.

good luck.
