Hello aspirant,

Yes, you can write KCET exam as many times as possible, even if you had not opted for the seat that you secured . The minimum age to give KCET exam is 17 years and the maximum age is 25 years.

Furthermore, You can also write the KCET exam if you have not opted for any college yet, but if you have opted any college, then it would be difficult to leave the course.

Further, to know more about the KCET Exam, application form, eligibility criteria, syllabus, course, etc - you can follow the below mentioned link to know more about it : https://www.careers360.com/exams/kcet

I hope that this will help.
