Hello Shivaputhrappa.

I guess you are doing well in this pandemic situation.

You can write the Exam for the second time as the KCET Examination has no limit. A candidate can write attempt as many number of times he want. So don't worry you can attempt one more time and do well in it. But if you select a seat  particular stream, then you will be not eligible to take the same stream next time. So keep this in mind.

You can check this link to get more information regarding the KCET:

Good luck...
