Hi aspirant...!

Hope you're doing great....!

So with regard of you're query. KCET( KARANTAKA COMMON ENTRANCE EXAMINATION) consists of 4 subjects physics, chemistry, maths and biology and each subject consists of 60 questions. You select three subjects. But you, can't able to answer the entire 4 four subjects because the maximum marks of the question  paper is 180 marks. you would able to answer for only 180 marks. so, you should select only three subjects. But for KCET 2022 exam pattern has changed there only 3 sections available here (math, physics and chemistry)

I am providing you a link below here so, you can check the information and update regarding to KCET 2022.
