I got 80% in puc board then I got 60 marks in kcet then my rank is??

You have scored a decent marks in board that is about 80%. But as we all know we don't get admission in Engineering or medical college through our board marks. So we all attempt different entrance exam to get admission in different college. KCET is one of them.

KCET is one of the entrance exam through which a local candidate of Karnataka can get admission in different stream like Engineering, Architecture and Pharmacy in Government or private college of Karnataka.

Eligibility criteria :-  candidates must have passed with minimum 50% marks in the 2 ^nd PUC/12 ^th standard or equivalent exam to appear for the exam. Also, they must have Physics, Chemistry, Mathematics/ Biology as compulsory subjects in their secondary education.

There are more than 200 colleges accepting KCET scores. Based on the marks secured candidates will be allotted seats into the institutes. Aspirants seeking admission in architecture courses must qualify JEE Main (Paper 2) or NATA and then they can participate in KCET 2020 Counselling. KEA will conduct KCET Agriculture Practical Test for those candidates who are seeking admission under Agriculturist Quota in Farm Universities. The test on “Identification of Agriculture Related Specimens” is held to claim seat under the quota .

The cutoff of KCET 2020 will consist of the ranks that a candidate has to secure for getting admission. Karnataka Examinations Authority (KEA) will release the cutoff after the end of each counselling round.

As you have scored only 60 marks in KCET , so you find some difficulties in getting admission on the basis of this marks because the minimum qualifying  marks for general category is 50%.  As predicated by me your rank on 60 marks is about in range of 18000-22000.
