Hi Thilak!

Below are the Eligibility Criteria for applying KCET 2021:

• You must have passed 10 +2 or equivalent with Physics and Maths as compulsory subjects.
• The additional subject can be either Chemistry, Biotechnology, Electronics, Computer.
• You must have studied English as a main subject.

From above, you must have passed 12th with the required criteria. So, I'm afraid that you cannot apply for KCET 2021!

Hope this is helpful!

All the best!
