Hello Siddesh,

In K-CET Exam for Engineering Aspirants, it is not mandatory to write Biology Subject. It is completely optional. It is for PCMB or PCB students who are appearing for medical. Even if you want to do MBBS then also it is not compulsory to Attempt Biology section in K-CET as NEET exam is compulsory for MBBS from this year.

Hoping best for your Future.

Thank You
