Hello aspirant,

Hope you are doing absolutely great.

So with regard to your query, YES you can write KCET exam as many times as possible, even if you had not opted for the seat that you secured. Further the minimum age to give KCET exam is 17 years and the maximum age is 25 years. So until the age of 25 you can give the KCET exam.

However, as you have not joined in the college that was provided, you need to wait for at least one year again to give another attempt of KCET exam as it is held only once in a year.

Hope this helps you,

Good luck, thank you.
