Hello,

No, you cannot sit for the KCET exam if you fail in Mathematics in your 1st PUC exam. To be eligible for KCET , you must pass your 2nd PUC (or 12th) with the required subjects, including Mathematics (for engineering courses).

You can clear the Mathematics subject in your 2nd PUC (12th) and then become eligible for KCET. But until you pass all required subjects, you won’t be allowed to take the KCET exam.

Hope it helps !
